I purchased a RAV4Screen + RAV4Phone in anticipation of receiving a RAV4. That didn't happen so I have no use for the items now.

Got them from here:

The RAV4Phone is just the bracket that mounts to the back of the infotainment screen with 3M weatherproof tape. I had it customized so that the end of the bracket is big enough to mount a standard AMPS mounting plate. I haven't drilled an AMPS mounting pattern into it yet. I'll leave that for the future owner. You can also use more of the 3M weatherproof tape to attach a mount to it.

Price is $60 shipped.
