I have a 2011 2306 and purchased the Jensen AWM975
The electrical connections were straight forward - I printed off both wiring diagrams and wrote down the color conversions so it would be easy to wire up.
I got it wired up but get zero radio signal due to the antenna connection not plugging into the back of the radio -
after looking at the back of the radio - it seems I was trying to plug the antenna into the Coax input connector and not the antenna hole which would make perfect sense why I didn't get any signal
I am in the process of adding a wooden frame around the radio to give it more room in the rear of the radio since the ZX75 was a shallow radio.
I couldn't believe when I pulled out the ZX75 the rubber around the radio felt gummy which was weird and the reason why I am replacing the radio is because the ZX76 would only power on with the remote and not the power button.
When I am done with the install I will post pictures and what materials I used for my install.
So far I have used Blue Butt splices to join the wires together.
Bought the wood from Home Depot but have not cut them as of yet - hoping to get that done today.
