From what I understand, replacing the stereo in my 2014 Patriot with the MyGig touchscreen radio, the only thing I really need to pay attention to is to get the low BUS and not the high speed BUS. Also, I'd prefer not to get an anti theft unit, from threads I've read it could be a PITA to get the security code. My question is - aside from those things, will any work? For example, I found a good deal on an REN unit, but it's from like 2008 - would that still work in my 2014 Jeep? Is there a year compatibility I need to look for? Thanks in advance.
