Whenever I get my income taxes in and get the truck paid off, I plan on upgrading my head unit. The old one is about to die so figure get it done while I can lol. I was thinking about a Pioneer AVH-4100NEX. Will I loose anything by switching to this unit? It looks like it uses Google Maps instead of standard Nav. Will this unit hook into my rear camera and such? I want a good radio that will sound better than stock with the Bose speakers and I don't want to loose any of the functionality I have now. Gain some is good loose any is bad lol. If this one sucks suggestions are great too. Thanks in advance.
