So I am upgrading from an older pioneer single din cd-plyaer to the avic z1 in my mk4 '02 Golf... I have the Monsoon stereo amp in the quarter-panel in my trunk; however, my old deck would wire through that amp via the normal aftermarket wiring harness just fine.... I did all of the hookups properly I believe, I hooked the remote wire to my aftermarket amp and hooked in the subwoofers and they are setting out a signal; however, I am not sure of any possible causes for no FM/CD/Navigation sound to work. Is there any difference in the outputs between these two systems that might require a rewire to bypass the factory amp? Thanks for your help!

might wanna get this moved to the Z1 section

hrm, im not sure why, i did click on the z1/2 page troubleshooting tab, but it just seems to link straight back to a root problems/troubleshooting page; however ive toyed with it a bit longer and still no luck =/
