Just installed mine. Works great. The instructions were a little confusing about orienting the output towards the passenger side and than I figured that was for the old version. The RCA's point towards the front unless you bend the the patch cables and you don't want to do that . I plugged the GLI into that first and there was just enough cable to route through the radio and out the hole next to the HVAC controls.
I actually just burned a music CD from Itunes and alternated it with the same songs on the Ipod and I can tell no difference. Best $80 I've spent on car audio.
