It's a '05 TSX. A few weeks ago my navigation started acting weird. It locates the car fine, so nothing wrong with the positioning part. It shows where the car is on the map perfectly when it's not doing the navigating. However, sometimes, not always, when it gives directions, it doesn't update the position changes quickly. So it will show me further behind on the route and doesn't catch up. But if the road turns, the red arrow indicating my car also turns. Since it's showing my position way behind, it turns onto some road I've driven past 5 minutes ago...

I know, it's a weird problem, even just to explain. Has anyone else seen anything like it? Thanks in advance for any help and advice.

 

i had a similar prob, then it started to get worse and worse, saying im like miles off ... acura tried to blame it on my tint so i took it off but prob still existed so they replaced the nav unit which finally fixed the issue and i had the tint reinstalled.

I took a video of it happening and showed acura the video on my cell.

 

I have seen a few here also, we have done a hard reset of the navi system and has usually worked but have also had to replace navi unit also. if you have tappered with navi unit in past make sure to clear any mods to system before taking it to us
