I’ve had 11 GPs and I can tell u that I have lost the date on some. Generally, I can get a decent pioneer with BT, USB for $90 US, metra harness for 35-40, and install kit for 10-12, don’t forget the antenna adapter maybe 5 bucks I usually just buy them locally. Metra harness wire colors match the pioneer ones so it’s just a matter of making the 11 connections (assuming not hooking up an amp, and no Monsoon) Monsoon system has a center dash speaker. Crutchfield will tell you what you need but I always buy on amazon or ebay.
