Hi everyone, new to the forum! Ive been having alot of trouble with getting my Pioneer Avic-Z150bh aftermarket GPS NAV installed in my 2010 SXT with infinity audio, here Toronto, Canada. Quick question and i hope there is an easy answer. Is it possible to have an aftermarket kit installed in my Journey, or is the wiring simply too complicated to have it done? ive taken it to a couple of authorized dealers (best buy and future shop), and they seem to be having problems.
