I'm planning on wiring up my Nexus7 in lieu of the stock head unit in my 09 SS/TC. Figured I'd start a thread on this project as I've been turning over in my head for a year or so, hoping emperor will stop in with some suggestions. I know I'm going to need a harness and amp to replace the headunit, thinking something like 4x50w that I can stash inside the dash. Ran across this guy, would cut down my wiring since it's Bluetooth.

Might be able to replace the amp entirely or get a cheaper amp that doesn't have Bluetooth. I'll be using the GMOS-LAN-04 to retain stock function.
