3rd Gen Radio Install Newb Questions

Hi all, I’m a long time lurker and have gotten tons of great info from past threads. I’m in the process of swapping out my entune radio with a Pioneer and I am stuck on two probably basic questions that I can’t seem to find an answer for:

First, I am using the Maestro RR with the Toyota harness, if I program the steering wheel controls I see button mappings for the right side. Does that mean I lose the control of the center display and those buttons control the radio instead? If so is there a way to program the left buttons only?

The second question is the Toyota harness kit came with two different backup camera connections but the diagram doesn’t make it obvious (to me at least) which version to use. One has two wires and the other has 4-5. Can someone confirm which one to use?

Thanks for your help!

 

As far as the first question just call iDatalink "Maestro's" tech support and ask them. I've never had a bad experience with their tech support.

As far as the Camera harness, you just have to pull the radio and see which one works.
