I'm hoping I am not the only one to experience this. I am taking the car in to Acura tomorrow but want to go loaded with info from the forum if possible.

Yesterday I noticed that when I started my '07 TL-S, the A/C was cleared, and by this I mean that the same setting should appear as when I turned off the car, such as AUTO, 72, etc... right? Yet all I got was a blank display.

Also, my Nav reset itself in the middle of my commute home. It went blank and then went back through the start-up sequence... disclaimer with the okay buttom.

Has anyone seen this before?

 

Never experienced this before! Maybe a soft connection somewhere? definitely take it to the dealership to have it looked at!

 

hopefully you turn all the ac stuff OFF not leave it in auto mode when shutting car down

The ac being on at startup puts extra load on the system- so does the stereo- turn all off!

You could have hit a big bump or gone thru a tunnel- related to reset of nav?

dealership here you come!

 

My navi from time to time has done the reset during my commute... not often. Plus I've also experienced the settings being flatlined. Never taken it in. (07 TLS)

 

So, it's now in the shop and I haven't heard a peep but on this thread I have a question. When I turn the car on neither the A/C nor the NAV/Radio come on until I have the car started. The A/C then starts low and ramps up. Also the radio and NAV then come on and the sound goes from low to last volume. You mention turning these off to keep the load down but the electronics seem to be engineered this way. Can you explain the reality of the start-up sequence?

 

Okay, I got the car back and of course, the tech found no problems. They ended up disconnecting the battery and holding the two leads together for 3 minutes to drain the caps in the electrical system.
Everything seemed okay until I noticed that the NAVTraffic was not coming up over the NAV (XM works fine but no traffic even if the icon is selected). I am now working with the tech on rectifying this issue.

 

So now I have a new NAVTraffic unit on order.

 

Did you try either calling XM or going on your account through their website and have a signal refresh sent? This might be worth a shot.

 

The ac compressor does not turn on until a few seconds after startup. The draw from the stereo is non existant too since this too takes a few seconds to come on and even if it were on immediately it wouldn't make a difference.
