I'm almost done with the stereo installation-
I mounted this 3.5 mm dash jack
eBay into a removable panel in the dashboard- this way an Ipod or other music player can be used if wanted-

In the dashboard -

Here are the controls for the Kenwood CMOS-310 Backup camera. The red switch turns the camera ON/OFF and the right switches control the camera mode & zoom functions-

I plugged in the camera and it works fine-

The Bluetooth dongle is behind the dashboard but here is the USB dongle- I routed it to a tray under the head unit and this can be used to upload images (wallpaper) or firmware updates. It can also be used to access a USB thumb drive with your music on it. I bought a 32 gb drive, uploaded my music to it and it worked like a charm-

I installed the microphone (for telephone calls) on the steering column-

The Power Acoustics amplified kept faulting so after ensuring that no speaker wires were shorted I got an RMA from Sonic Electronix and will be sending it out tomorrow for an exchange - :(:
I did get the camera cable completely routed from the cab to the area under the shower area in the back of the coach. That is where it will connect with the camera cable- I stall have to mount that on the back to finish the install.
More later-
