Hey guys. I picked up a 18 Mirage GT and I'm really enjoying this car just two days in.

The GT only came with mats so I'm looking to possibly pick up the Rockford package (AMG14EAB01) and remote start package (MZ360477EX). I believe I saw on here the Rockford package was plug and play but I haven't seen anything about the remote start. Can anyone provide brief information about the install?

I'd take it to the dealership but the sales guys seem to just chase their tails. They also want 20% over MSRP for the parts.
