Tyzing

Alright guys I bought this info on ebay for like 7$, I honestly don’t think he should be selling it when people in other forums are trying to help for free, although if it was the DVD with different file structure then I’d understand for the charge, anyways here ya go, email me if you have any questions Tyzing@hotmail.com


Congratulations on purchasing the AVIC bypass tutorial...

First off I need to stress to you the following...

- It is illegal in all 50 states to have a video source within view of the driver of an automobile...we will not be held liable for any accidents, tickets, fines or criminal charges, consider yourself warned.

-Any modification done to your Pioneer unit will void your warranty with the manufacturer again we are not liable for any damages done to your unit.

-If you do not feel comfortable with soldering, schematics, relays etc. please do not attempt this on your own...please find a qualified professional.
- Please feel comfortable to contact me with any questions or comments. I am here to help you.

-Lastly, NO REFUNDS...I am selling information...once the information has been attained there is no way to return it.

OK, lets get started!

First off there are a few systems you need to bypass...

- The Parking Brake.

- The Vehicle Speed Sensor.

- The Gyro Sensor.

Now that we have gone over what needs to be bypassed, lets find the first system to bypass, and how to bypass it.

The parking brake needs to see 12 volts (positive trigger) then it needs to see a negative trigger (i.e. the negative side of the parking brake circuit) To do this we need to wire in a relay to a switch to trick the AVIC into thinking it is connected to a parking brake..please refer to Figure 1. (I have also sent you some more detailed diagrams via email)




Next we will move onto the Vehicle Speed Sensor (VSS) and Gyro section. This section bypasses the navigation so that the software does not tell the unit player that the car is moving. Thus, navigation will not be accessible while this switch is activated. Basically this setup tricks the car into thinking the VSS is not hooked up and the GPS antenna is not hooked up. Figure 2. (I have also sent you some more detailed diagrams via email)



Now there are 2 different ways to wire up the Gyro cutoff relays..you can either open up the brain and cut the circuit between the Printed Circuit Board (PCB) and the GPS antenna input. Or you can cut the GPS antenna and wire the relays into that. Either way has its pros and cons..(If you connect to the PCB you need to open the brain you risk damaging a very expensive part of the unit) (If you connect and cut the antenna your GPS may not work...The wire on the GPS antenna is specifically set at a measured resistance , and introducing a relay may disrupt that resistance, but that GPS antenna is much cheaper than a Brain) That is your decision to make .

Now that you have everything hooked up all you need to do is activate the switches and VIOLA!

Also here is another email i sent him about the install:

In a message dated 7/5/2005 8:17:04 P.M. Eastern Standard Time, YMCARacquetball@hotmail.com writes:

Can it still work if you cut the antenna instead of the brain...if was i was to do it that way (antenna) what is the chances it'll work 80% or so?
__________________________________________________ ______________
I would say a 50% chance of overall

I would Highly recommend to do it at the brain itself

With that being said, I think if you do the antenna if it should still work...I just don't think it will be as accurate.

The GPS antenna is a measured length, therefore it has measured resistance...It was built with the intention to never be cut.

Again, I would try to do whatever it takes to do it at the brain for best results. (maybe bring it to a local car stereo shop and have them wire it up)

hope this helps...

Good info. thanks for sharing it with the rest of us..

I have no clue what that dudes problem is.. All cleaned..

Tyzing

thanks jonesi, i was hoping i wasnt the bad guy here!

Thanks for the posts man! This is very interesting! I wonder how well it works

Tyzing

I've talked to a few people who have found success....I've even talked to people who cut into the antenna which is supposed to be very tough to make work, and thier's works well....only get it done at a trusted shop and some where that will stand behind their work.....My installer didnt have a problem doing it but of course a new DVD would be much better

Tsx536

I just upgraded my Pioneer AVIC-N1 with the latest software and maps. This it made my AVIC-N1 become an AVIC-N2. I found out the hard way that you can't revert back to the AVIC-N1 software once you load the AVIC-N2 software.

With the help of this thread I was able to get the Navi/video to work while I'm in motion!! I installed a toggle switch and a relay on the VSS wire. I ended up wiring some things differently with the relay and GPS antenna, but the logic is pretty much the same. Now the Navi will let me search for gas stations and fast food while I'm moving again, just like my N1 did. I can also get XmTraffic now if I want too

Thanks for the info Tyzing!

Tsx536

Got your PM Tyzing. I can help you out.

Are other people interested in how the bypass is done? I'm wondering if I should just post in the thread.

NeonShark

Hey Tsx536, how did you update your Avic-n1 with the latest software to make it an Avic-n2? Where did you get that software? Thanks

doublern2003

even better make an iso out of the dvd and park it somewhere...if needed you can host on my ftp

I got everything hooked up I had a professional do the job for me. He did the bypass. I can use my navigation while I drive. The problem is when I go over 10 mph. Then I lose some of the input buttons. I guess he might have did something wrong. I thank you for getting me to use it so I don't have to input adddresses while I'm in park. I can wait for a light or something that will slow me down enough to input things. I would like to know what he didn't do, so I can take it to another installer and tell him what to do to stop bypass the gyro thing. Thanks again

Tsx536

He hasn't fully bypassed your system.

When you turn on the deck. Go to the Navi-->Settings-->Hardware info.

When you drive what values are you getting for the following:
VSS wire --> How many pulses?
GPS Antenna --> OK status or NOK status?
Parking brake lead --> High or Low?

You need to check these signals when your car is motion and you have your bypass enabled.

|I've got a super easy way to do it, requires soldiering one wire and you do not have to take apart the AVIC-N2 nor do you have to CUT any antenna wires=)

PM me for details.

StreetEffectz

OK, we figured out the real way to bypass the lockouts on the new
Pioneer nav systems. It is real simple, and does not require any
complex switches or anything. This bypass will do two things:
1. Makes all nav functions available while driving (just like they
should be)
2. Make video playback available while driving

AVIC-N2: Underneath the unit is a small silver sticker, peel this
back. There are two contacts with the label "R197". Drop a bit of
solder between these to connect them.

AVIC-D1: Find an extra Pioneer wire harness, and pull one of the wires
out. In the AVIC-D1 harness, there is one open spot on the connector.
Put this wire into the open spot on the connector, connect it to
ground, then re-connect the plug to the AVIC-D1.

Thats it, real easy.

Tsx536

With this method you guys are talking about, do you still need to ground the parking brake wire?

rn4emp

I have an avic-n2 is this the only step I have to do to get this thing to work?
AVIC-N2: Underneath the unit is a small silver sticker, peel this
back. There are two contacts with the label "R197". Drop a bit of
solder between these to connect them.
Or do I also have to do the d1 part of it?

nismo

Please do not drop a bit of soldier, and no you do not have to do what the D1 is

Just ground out your parking brake wire and solder a wire across these two points.

USE A PIECE OF WIRE, about 26gauge.

DO NOT DROP SOLDIER, if you look carefully, there are traces around these two points that absolutely cannot be contacted. It was hard for me to do because these points were so small and that the wire was so thin.

If possible bring it to an electronics repair depot, get them to do it, you cannot use the regular soldiering irons from radioshack those aren't fine tipped enough, unless you feel like screwing up your avic-n2

I did two of these today and they work absolutely fabulous. But it requires a special super fine tipped soldier iron that heats up 10X more than the average to get that soldiered on right.

Tsx536

Are the points as small as on a Ps2 or Xbox modchip?

nismo

i've never modded my own ps2 or xbox so i can't say, just peal the sticker back and you'll see the two contacts.

StreetEffectz

Hmmm, guess we're just good with the ol' soldering iron

nismo

uhh its not about that, its just to do the job right. you don't wanna hack it right.
streeteffectz your suggestion of dropping some soldier inbetween the two points, not a bright idea.

rn4emp

I looked under the headunit and I didn't see a sticker. or is it under the grey box comes with the headunit

nismo

its on the head unit, its a silver sticker that is supposeto blend in with the chassis.
IS YOURS AN N2?

drew22mader

So no more cutting wires and using switches? I'm going to buy my AVIC-N2 next week and i'm making sure the bypass for sure 100% works. Does everything still work? Can i put in new locations while driving? Have you messed up any or damaged any by doing this? So i just take a 26 guage wire and solder the wire to both point and i'm in business, do you have any pics of the underside with the wire on?

rn4emp

yes it is but I see a red sticker and I felt every sticker and I couldn't fell any bump to let me know that I'm peeling the right one. In fact I'm going to peel all the stickers. lol

rn4emp

I found the silver sticker and solder the the two points and it works great.

StreetEffectz

I solder a small piece of wire in between the two points - I've also soldered the two points together - been doing this long enough to trust my own abilities. For the everyday do-it-yourselfer, sure, dropping solder between the two points isn't the best thing to do.

And I didn't realize soldering two points together nicely was considered "hacking"

pcguy760

Hi, I have a few questions about the N2 bypass :

1.Does it allow you to use ALL functions?
2.Does it display the full Navigation map while driving and does it still display the Vehicle Dynamics?

Has anyone else did this to their N2? I want to get a N2 if this works

StreetEffectz

Yes, ALL functions are available with this mod and all displays are available too

pcguy760

That's great - Thanks for the info.

mantis23

another success, drop some solder, ground the parking brake.

Thanks Kamlung!

mantis23

didnt see any mention of grounding the parking brake, but we had to do that in addition to dropping the solder.
