What would cause the gps screen to be not working all the time. From time to time it comes on so I know it is not the actual screen itself. Also, the headlights will run full time no matter the setting, off, auto, fog, or on. Then, just for fun, they turn off drving down the highway. Spinning the setting dial will get them right back on. Don't know if they are related but it's both electrical. I figure there is some short along the way where the command screen / gps isn't getting juice and I think the headlight switch is probably bad.

Electrical problems can be a nightmare to find and can cost big coin so I'm trying to figure out if I'm going to trade or fix. Any idea what I can expect to pay for this repair? BTW, i's a 300 C level.

Any and all suggestions, help, answers are greatly appreciated. Thank you!
