I use a Sony head unit as you can get a motorbike remote which I have at the end of the transmission tunnel -- this saves either fishing around for the normal remote or diving under the dash. I also have the rear speaker outlets wired to a 3.5mmplug which I use to plug in motorcycle speaker earplugs -- removes the wind noise and lets you hear all road / car sounds with the radio at a low level!
