I recently ordered a Pioneer Premier AVIC-F90BT for my 2006 Ford Mustang GT which has the stock Shaker 500 system still in it. I have been doing some research on what wiring harnesses and adapters I may need to do the install and have found conflicting information. Crutchfield says I need the PAC C2R-FRD1. One local install shop agrees with them. Another local install shop says I don't need it. Some web forum posts say I need the Metra 70-5521. Other posts say I need the Metra 70-5511. Some say I need a RCA Y adapter. My local install shops say the F90BT does not support Ford's Volume Speed Sensing feature, yet I've found posts that say it does. I don't know who to believe. I want to do this myself, so here are my requirements.
1. Retain the Ford Accessory Delay feature where the F90BT will stay on for up to 10 minutes or until a door is opened.
2. Retain the Ford Volume Speed Sensing feature where the F90BT automatically increases its volume as the vehicle increases speed. This is not important, but is nice because you get quite a bit of engine and road noise inside a Mustang GT and I don't want to have to keep raising and lowering the volume as I speed up and slow down in traffic.
3. No "pop" sound when the F90BT is powered on.
4. All of the features in the F90BT function fully.
I will not be replacing the stock speakers or amps at this time. What wiring harness(es) and/or adapters will I need to install the F90BT in my 2006 Ford Mustang GT while getting all of the things I listed above?
