Well finally got it all done and wanted to share it with all of you. The audio system is a Kenwood compact digital controller with blue tooth 400w marine grade. The subwoofer is a compact Alpine 100 that is tucked up under the dash and mounted to the frame rails. The speakers are marine grade and you can see one of them mounted on the side. It sounds much better than any overhead mounted unit as the floor area provides lots of surface "boxed" area to direct great sound and deep base to the riders.
The GPS is a Nexus tablet with Orux installed (many threads on that here). I love that system. A big screen that my passenger can use and I can see also.
Cheers
