When I bought my RL my Nav Disc had a substantial scratch in it. I took and had it resurfaced which returned it to new condition. On a recent trip the person driving my car hit a HUGE pothole the size of the car. Immediately after the NAV gave me an error. I checked the disc and sure enough its scratched (same as before).
Any one else have any NAV disc / pothole related problems?

 

Its probably something loose in your dvd unit cause i have no scratches on my disc and i have a huge 15" subwoofer pounding the crap out of my trunk. I only have the door to the dvd unit pop open every now and then when i o.d. on the volume.
