I recently finished a non-Navi to OEM Navi conversion and everything works perfectly. However despite using all new OEM components including all of the required Navi OEM wiring harnesses, I can't get the dash digital clock set. I am using the latest software (just got it from Alpine, it's v3.5) and set the clock in the Navi setup (menu 4), but the clock on top doesnt' change.

In looking in the owner manual (don't have a Navi manual) it says that for Navi cars this style clock is set automatically. Set by what is my question. There are no buttons like my old non-Navi digital clock had. I figured that it was set by the Navi software but apparently not.

Any help would be appreciated as at this point I can only set it by connecting the battery at 1:00 and is a bit of a PITA.



As a side note, the software I ordered from Alpine for my 04 TL has a Honda logoed splash screen instead of an Acura one. Is this normal?

 

Mine set automatically when I did my conversion. I'll call my installer and ask him. Good luck.

 

So it's SUPPOSED to be set by the Navi software...as in when you set the clock setting in the navi setup, it's supposed to change the clock up top.

Does your navi software's splashscreen have an acura or honda logo. I'm wondering if I have incorrect software that is missing clock support just as very early versions didn't have XM support.

 

how did you go about doing the conversion? Did you take it to a shop or do it yourself?

 

Myself. I got the hard parts from Del Ray Acura and the wiring harnesses locally from Tustin Acura.

Parts List I used for my conversion with automatic transmission.

In addition to this there were 3 wiring harnesses but I don't have those part numbers in front of me. A dash harness, a ceiling harness and the harness that goes from the front to the trunk. Note that the dash harness is transmission specific, there is 1 for manuals and 1 for automatics. What I did was printed out the harness pages from Del Ray Acura's parts store. I printed one for my non-Navi car and 1 for the Navi version of my car and bought the 3 harnesses that were different. The 3 harnesses were expensive...$1150 with tax. From Del Ray Acura they are a few hundred cheaper, but it's certainly no wonder that people want to make their own.

In addition, contrary to the parts illustrations, the Navi disc IS NOT INCLUDED with the DVD drive. It was an additional $207 (with tax and shipping) from Alpine for the latest orange disc v3.50

I also bought the service and electrical troubleshooting manuals. Because I didn't make my own harnesses I didn't use the elec TS manual, but the service manual was a MUST and is worth it's weight in gold. The elec TS manual is a must for making your own harnesses.

The installation took me about 15 hours. The major project to my install was removing the dash. Since I opted to use the pricy but OEM harnesses taking out the dash was the easiest way to get the harness in. Using the service manual it was easy, just time consuming. But then hooking everything up was a cinch, just plug and go. The headliner had to be dropped for the ceiling harness (for the mic) and then the typical package tray and seat removal for the GPS antenna.

I had 2 issues with my install. First was me buying used GPS software on EBay. I originally got a very early software version, I think it was 2.1 and it didn't have XM support. Everything worked, but when you went to Audio on XM you just got an AUX screen, no XM details. The second is the one that I still have. The new digital clock display over the navi screen plugs into the Navi system. It is supposed to be automatically set by the Navi software but it mine it's not. Yesterday my v3.5 Navi disc finally arrived from Alpine. I had assumed that the old software simply didn't have clock support just as it didn't have XM support, but after installing the new orange disc, the XM screens worked, but the clock still doesn't update. I am only able to set it by connecting the battery at precisely 1:00 which is the time the clock turns to after the battery is reconnected.

No doubt the cost of this conversion is insane but at the time I bought my car in early 2004, there simply was no Navi cars to be had in SoCal so if you wanted a TL, it was sleep at the dealer or take a non-Navi one. And having wheels, exhaust and the blower...and no original parts (sold them) selling the car to get Navi wasn't an option. But despite the price, I now have the exact car I've wanted since getting it and that is all that matters to me.

 

You shouldn't need to set the clock with Navi. You set your timezone and it will set and correct your time based off the GPS time.

 

I went into the Navi setup, make changes, pissed around with the settings, but the digital clock on top doesn't sync, change or anything else. It's as if it was disconnected from the Navi, yet all of the other functions of that display work fine.

 

Can you post pictures of the finished installation? Thanks in advance...

 

it should set based off GPS time...how accurate are your coordinates with the new navi?

 

why dont you just disconnect the battery then hook it back up at noon? shouldnt that reset that clock since it is apparently not synching with the nav?

 

are you getting sync with the satellites?

 

skeedatl
How did you deal with the new 4 button hfl unit on the steering wheel? Did you have to buy the cable reel harness for that part of the install or did you use the existing plugs and rewire the hfl unit to the micro phone in the headliner. You must have a fortune in your navi conversion. Did you go with all new parts from the dealer?

 

EVERYTHING works perfectly except for this clock issue. Position resolution appears to be about 15 ft.

 

Yeah. Navi works, voice recognition works, XM integration works, new HFL buttons work, the new instruments (clock, XM summary, AC display) works. It's just the clock is wrong.

 

I thought that may be the problem and I did disconnect the battery. But when I reconneded it, it just stayed 1:00 and has kept time from then every since. Mind you it started at 1:00 at around 6:40.

 

As I mentioned in my original post

I could certainly do that. However, being as I spent a small fortune and used all OEM parts, this is bugging the crap out of me that it doesn't work like it's supposed to.

 

I was going to suggest the same thing.

 

The details of my install are in post 5. I bought all of the OEM harnesses including the entire dash harness and the roof harness (along with the harness going to the trunk. Yeah, it was expensive and I did buy all new parts. But as I mentioned earlier, when I bought my TL there simply were no Navi cars to be had and even then, they weren't being discounted. So back then Navi if I could have found one would have been aroune $3000 (since they were discounting the non-navi cars by $1000 more than navi ones). I spent about $5500 to do mine with all new OEM parts. And since I have other mods and none of the original parts, selling the car and getting a navi one I felt wasn't a good option.

 

And I'm sure that would work, but G-D-it this stupid thing should work like it's supposed to. Grrrr...frustrating

 

The finished install looks EXACTLY like every other Navi car. With the exception of my drive cover. I have never seen a Navi car so I don't know how the drive is mounted from the factory. Mine is just flat in the trunk and I made a drive cover for it cause I couldn't find any special carpet kit or trunk mount.




Navi works (even sees I'm in a parking lot next to the street) but of course the clock is 4+ hours off.

 

Maybe it's a bad unit? Try calling a few dealers for suggestions, not to mentioning your conversion, and ask them if they've seen any navi units not updating time correctly...

 

sine you have the honda splash screen your car may be loading the incorrect bin file but i dont think that would mess with the clock try reading on the hack you navi threads to learn more about the bin file

 

So Acura's have an acura splash screen correct? This could explain it. Perhaps "Honda" software doesn't have clock support. This new disc I bought, I got directly from Alpine and supposedly it's for my 04TL...orange v3.50 disc.

Thanks for the insight...I'll look into this.

 

I was just thinking....

When I put my system in I bought an orange disc off EBay. It had a Honda splash screen. I'm now wondering if my 3.50 disc I just got simply saw what was on there (in the firmware) and updated that, meaning if I has started with the 3.50 disc, it would have installed Acura firmware.

Does this make sense? If so, I wonder how I would go about resetting the DVD drive to "new" condition so that it would see the 3.50 disc as a new install.

 

On this last revelation, I found out what my problem is. When I installed the original disc, it was for an accord. When I put in the new disc, it just updated the accord software. This explains the splashscreen and lack of clock sync support.

HOWEVER, I do have the trip computer (although it's not really accurate) and the calculator which people here seem to want in TL software.

Personally I would give them up to be back to OEM, so now I'm trying to figure out how to force the unit to take OEM software....that is unless Alpine sent me the wrong disc and multiple versions (eg TL, Accord, etc) aren't on a single disc.

 

ALL FIXED! Thanks to all those who contributed to this thread as this brainstorming got me in the right direction.

Turns out my suspicions were right originally and the poster who mentioned the Honda splashscreen got the ball rolling. The Acura software does indeed have clock sync support and the clock sync will not work with Honda firmware. When I did my original install, I bought a 3.1 (thought it was 2.1 but just looked it's 3.1) disc off EBay. When I installed it, it installed into my new Navi system as Accord software. So while I had the trip computer and some other non-Acura features, I didn't have XM or clock sync support.

Figuring the clock and XM support were just not in 3.1 I got the 3.5 disc from Alpine. But since there was already Accord software installed, it just updated with newer ACCORD software, so while I got XM support which is present in the Accord, I didn't have sync support which is not an Accord feature.

After some searching, I found a thread on software swapping from those who choose to run Accord software for the trip computer and other goodies Acura-ware doesn't have...and followed these directions from that thread...

And then followed these directions on how to do disc swaps after getting to the diagnostic screen and then to the VERSION screen.


Using this method I forced the Acura firmware to be loaded over the old Accord firmware and now everything is fine. No Accord trip computer anymore, but now I have the Acura splash screen and the clock syncs like it's supposed to.

So to those who have noticed your clock not syncing, it could be because of the software you're running if you're doing Navi hacks.

 

Anyone have the Newsletter Discount code for ordering parts from Delray Acura?

 

good job

 

AC010 for an additional 5% off. Expired 4/1/06 I got 2 newsletters from them and both were 5% off coupons.

 

I'm just thankful it worked. With a projects this big, like the blower too, I'm always surprised they work when I'm finished. I'm always sure I missed a step or screwed something up. If the clock thing is the biggest problem ever I have with these projects or the car itself I'll be stoked.

 

thanks

 

glad to see you got it working and my bin file tip was acutually what helped you

 

Absolutely helped. Thanks a mil!

 

Sooo if i were to get the oem nav screen/hvac only.. then i can only change the clock by pulling neg. cable out of the battery and back in????

 

Yeah. WHen the batt is hooked up the clock comes on as 1:00. So if you were to do it at 1 in the afternoon every couple of months it would be accurate. But you would still need the wiring harness as the clock plugs into the Nav. And if you're spending that much for the nav screen and hvac screen, you might as well get a drive off ebay as well, make some harnesses, pick up an HFL button and have the whole package.

 

Your right skeedatl, i think the hardest item to come across is the harness since its so pricey. Do you happen to know anyone that can make that in so. cal??

 

Actually I didn't even look. I do have the electrical TS manual and it's pretty straight forward. Using that I suppose anyone with soldering skills could do it. It's just a matter of them buying the correct connectors. I wanted an OEM install and given the stupid amount of money I was already into this project I just bent over and took it in the A for the OEM harnesses. Given how much the connectors are, the amount of time it takes, IMO it's a better deal to spend a few hundred more and buy the OEM harnesses. One person mentioned they found someone to make the harnesses for $700, but you can buy them for not much more than that. I paid FULL RETAIL and it was $1150 with tax. From a discount dealer like Del Ray Acura (delrayacura.com) you can get them for several hundred cheaper...I'm guessing in the $800 range.

 

I have decided to take your route on installing my factory navi. My installer bailed on my project leaving me at square 1 and from talking to other installers it is going to be the same price either to have them build a harness or replace the factory harnesses. I am somewhat ahead of the game money wise cause my parts guy threw in the harness from the trunk to the dash and the rightside dash harness when I bought the hardware for the install. Is there any way you can pm me with the part numbers for all three harnesses so I know I have the right ones? Looks like the money I saved on the harnesses will go out to the installer for he wants $1000 to $1500 for the install. Thanks for your help!

 

hey skeedatl , i have an 04 tl could i convert to navi using all 05 tl navi parts , nav screen, dvd rom, all harnesses to the 04 stereo, i think they would be the same. went to del rays site and checked the price on harnesses and 04 were more than the 05 for the same part . could this be done.

 

I haven't done this but I'm 99.9% sure its the same everything. Just make sure that if you purchase the 'dash' harness its the one that corresponds to your transmission.
