Installed mine Friday/Saturday. Relatively easy install as long as you can follow instructions. Only took 20min or so to get the radio out taking my time. Brought it inside and disassembly/reassembly with the board probably took about 2 hours, but I'm slow. I don't solder, so that part scared the shit out of me but turned out fine--maybe used a bit too much solder but it piled up nicely and touched nothing but the wire and the contact point! woohoo!
Put the radio back in and everything sounds great Headed to radio shack today to pick up a female jack to mount in the cubby, also still have to do the switch.
Thanks, Sebastian. great product and awesome instructions to go with it.
