Right, so today, I decided to use my navigation to find a post office but in the midst of typing in the address, the screen becomes unresponsive to my touch. I turned off my engine and turned it back on to see if restarting the navigation would do the trick it but it's the same(I noticed the screen was pretty warm to the touch as well). The warning screen remains but I can't press agree. I can't even adjust the vents and audio settings anymore. Does this mean I have to go to the dealer?

 

You may want to pull the fuse to give it a true cold reset, but unfortunately most people with that symptom have had to replace the unit due to a faulty touchscreen digitizer.

 

Thanks for replying! Ugh. This sucks. Do you or anybody know how much it would cost to replace the bloody thing?

 

mines just went out about a week ago. If your car is under warranty they'll replace it for you for free. It was around 2k for the unit, lucky warranty covered it. What year is your car?

 

Perhaps look into aftermarket offerings?

 

Exact same thing happened here on a 2008 ISF, NAV didn't respond to touch commands.

Warranty replaced the entire display, but if out of warranty, the screen is a $4-5k part alone...

It went bad once, which means it could very well go bad in the future once the car is out of warranty. Does anyone know if there are people who replace/repair the NAV screens? Or does the non-NAV core fit cars with NAV?

I bought my 07 IS250 used with the 3 year or 100,000 miles warranty. That should do the trick, yeah?

 

2000 for the glass unit.
