I purchased an '05 TL with nav a week ago. When I purchased it, the battery was dead from sitting on the lot, so they jumped the car. Since then the battery has been working fine. The problem is with the clock not updating itself. My top dash time is wrong all together. I've tried going into the setup area and changing the clock, however in the setup screen it shows the correct time but STILL does not change the clock in the small top dash screen. Any one know what the heck could be the problem? Any work arounds?

 

Bump.

My battery went dead while sitting in the garage so we got a replacement battery and now the voice prompts won't work for navigation (HFL works and audible) nor will the time correct itself according to the navigation, I'm getting close to wanting to take it to the dealer but hoping I could get some suggestions, I tried resetting the navigation but no progress made.

 

both of you should try reloading the navigation rom. you may have the wrong version loaded. this option is in the setup somewhere (press and hold map, menu, cancel)...

 

unfortunately that didn't seem to fix my problem. I went through every menu in that setup screen and nothing seemed to affect it. I think I'm gonna try pulling the battery at noon and see if that solves the problem...

 

Thats Funny im having the same issue and tried everything you guys just stated and still the same. I guess i have to pull the battery

 

Just wonder you guys are able to make the ajustment on the dash clock yet? How?
thanks !!!
