I recently tried to update my navigation system with the new 2015 map CD I bought from Toyota. I removed the original 2008 map CD and put in the 2015. It just started making weird sounds (clicking) like it was trying to load the disc - unsuccessful. When I pressed eject it did nothing. Finally had to physically remove the disc with tweezers. Tried re-installing the original 2008 map CD - same problem. Now my navigation and screen/radio doesn't work. I spoke with Toyota and they said I would have to bring it in and they will take out the navigation system and send it off to have it repaired. I haven't done it yet and I wanted to see if others have had the same problem. It seems to me, Toyota should take care of this problem free as it is the only time I have done anything to the system. Oh, yeah - I was quoted a new system would be $500-$600. Please let me know soonest!
