Okay, got the PA15-HON2 installed today. Hardest part was the dash/radio removal....etc. But I do have a question. The ipod works when I plug it in, but on the NAV screen it just goes to EXTENSION and plays whatever the Ipod was on. I can flip through songs by hitting the seek/scan buttons, but the touch screen option doesn't pop up. I read where that only works on vans with an XM button which mine has but it is on the lower radio unit which doesn't do anything when I hit it for this. So not sure what my options are. Any input is appreciated. Thanks.
