Ok, so here's the dilemma... My husband just bought me a 2008 gmc yukon. It is a non bose model and has the after market rosen gm0710. I like the layout of the head unit with the back up camera, BUT there's just so many problems. For starters, I can't figure out how to get the NAV to work. It just keeps taking me to the screen calibration part and when it says "tap ok to continue" there's no ok button!! Also, the sound quality in my car is terrible! I love my music loud but this is probably the worst sound system I've ever had... Any help with tips or suggestions would be great!! I'm guessing the best/cheapest option is to get just new speakers for the sound part of the problem but do I need anything besides that such as an amp?? Stereos/speakers are probably my least knowledgable area do I'm so stuck!
