Need some stereo help...touch screen

Hey everyone...Im looking for some assistance with figuring out what may be wrong with the touchscreen on our 4Runner: 2011 4Runner, Limited with touchscreen/Nav...the touch screen stopped responding to input a while ago when I was deployed. My wife took it to the dealer while I was gone and they said the whole system needed replacing (upwards of $3500).

The stereo still works with input from the steering wheel controls, but obviously anything that requires typing or touch option is not working. The most glaring loss is the bluetooth, as my wife can no longer pair her phone.

I find it hard to believe that the whole system needs replacing, but I could be wrong. I did a search here on this site, and didnt find too much info on this except trying to pull fuses to "reset" the software, or maybe the software needed updating.

I went to the dealer today, armed with the knowledge of the software, and didnt get much help except to "bring it in and they would check".

Before I shell out the $ for the dealer to "look" at it, has anyone had any experience with this issue to the point of being able to fix the touch screen?
Is the software update a legitimate fix?

I also looked into dropping in an after market radio, and the cost is waaay cheaper, but I'm looking to retain the back-up camera function. Is there an after market radio that will retain the back-up camera?

Thanks in advance for any assistance given.

Matt

Hi Matt,

You can perform a HeadUnit Master reset which usually works. Just look under the hood an see the main fusebox. Open it and see a Green fuse labeled 30A AMP Fuse. I think it's in the center row towards the firewall. Pull that fuse out and leave it out over night. Doing this will Clear out useless, damaged temporary files and corrupt idle logs from the registry/cashe in the units Hard-drive/processor; which will cause the unit to reset to it's DEFAULT, factory settings!

PS: This fuse MUST remain out for a minimum of four hours. You can still use the vehicle but you just won't have any audio or navi function!

If that doesn't resolve the issue, you should take the truck to " a different Toyota dealership". You likely do not need a whole new headunit but rather, a later version of the operating system software download...which is installed for free!

Best to you!

I haven't done anything with the fuses or power, but it seems to be a recurring suggestion...as soon as my wife gets home I will disconnect the battery, and if that doesn't work, I will try the fuses.

Thanks again for the help.

You don't need to disconnect the battery to reset the HU. Just pull the fuse to restore the hard-drive to it's default performance. Many here have had this issue and pulling the 30A AMP fuse and leaving it out (min 4 hrs) solved the problem!
