I've had my x910 for about a year & used mods in the past. However, it started resetting automatically when I turn on the car. I can manually reset it & get the audio to work, but the navigation point is stuck at the place it originally started messing up at. I've checked the wiring & everything appears to be the same...I've called Pioneer & they say I have to return it to them. Does anybody know if I can troubleshoot this? Also, if I do send it back, should I take off all the mods I put on the system so there isn't an issue with them about warranty & what not? Thanks!

Odd are all they are going to do is reload the software and see if it starts up. Thats their sop. They prob wont even notice youmodded it. Granted if they do they may void your warranty. Better normal it up to be safe.

Thanks...Will do. Hoped that way would help it, but it didn't unfortunately.
