The only way to go

I recall reading some reviewers saying the chime was intolerable. That must be fixed as the chime and blinkers in my unit sound the same.

Installation was straightforward. It's nice to be able to carefully make all connections before getting in the vehicle. It is a bit pricey, but I think very worth it to maintain all original factory functions.

My installation advice is sit at a table with all instructions. Be patient, pay attention and double check each connection is what you intend. Write down ( or even photograph ) each wire connected for future reference. If there are problems when the radio is installed, it may help troubleshoot before you have to pull the radio back out.

All this said, don't let any of it intimidate you. There are a lot of wires, but with just a little study time it all is clear.

Finally, after my install everything works in my 2012 GMC. OnStar and factory XM still function. Although the satellite is now an auxiliary input and has limited information in the driver information display. Not an issue for me but some may not like. The only item that seems a tad flaky is after an OnStar call, my pioneer unit is returned power and must go through the entire cold startup. Again this is not so much an issue for me as I very rarely use OnStar calling, but others may feel different.

Good luck to all!

Great product

Really easy to install. When plugging a couple of the connectors in I feel they didn't push in and had a tight connection, but then they were snugged in tight. Really good product.
