im tryin to figure out what to do.. my f700bt will play music from my ipod and cds, but when it boots it shows the splash screen, THEN goes black i can still change songs and what not but i cant acess the menus or anything.. my gf used my truck a few weeks ago and she said some ezrider error came up she pressed map and it worked ok.. after she got back i checked it out and its been doing the black screen ever since.. a few times i could hit menu and it would work fine.. but as of late the screen just stays black.. any ideas?
