hey guys on my way to school this morning i started my car and noticed that my Navi screen was not working properly. The radio does not work nor does any of the display unit buttons, the navi screen goes to the "OK" screen. When you go to touch the screen it is unresponsive..

Please help me, I really hope this isnt a expensive fix

Thanks guys!

Before you start panicking....Check your fuses chief! If good have you been behind the dash recently? Check all molex connectors...

Disconnect the negative terminal of your battery for 5 minutes. NOTE that you will need your radio and NAVI codes after this procedure. It should reset the NAVI unit back to stock. If you hacked the NAVI, you will need to re-apply the hacks, as well.

tried this and when i tried to put my codes in the screen was still unresponsive

any other suggestions!

^^ Looks like it is the ACC fuse #32 in the under dash fusebox. This may be the culprit if you have used this socket to power anything else (footwell lights, NavTool, etc).
From the Electrical Troubleshooting manual, section 6-2:
Fuse #32 7.5A Accessory power socket relay, Audio unit, Display panel control unit, HFL control unit, MICU, Navigation unit, Shift lock solenoid

Also check fuse #7 in the same location---looks like that has some NAVI functions tied to it, too.
The underhood fusebox feeds both of these fuses in the underdash panel. Check fuse #15 it is a 40A fuse.

Any auto parts, hardware or Walmart store. You want the mini-fuse type.

Not sure at this point. Could be a failed touchscreen controller or some other component, at which point it would probably need to be addressed by the dealer. You still under warranty?
