Yes, the U-bolts do not work on the Solera based on the dash design. On Ford and Chevy they work just fine. (darn germans).
Unlike a car...this one has 5.1 surround. So in addition to normal dash speakers, there are wires for a 2nd zone (so to speak) sub, GPS, Audio in, audio/video out...as they say in Canada... It's a dogs breakfast.
