Hi. I’m new here. I have a Avh 7700bt, was wondering if there’s any software hacks, etc. just bought this radio, and wondering if any hacks as free gps YouTube etc. I connect my phone and there wanting me to subscribe to services for fees. I have a iPhone 7plus so car play doesn’t work with radio, and I have tried to use waze and some navigation on phone but doesn’t work in responsive. Can any one help please?
