I have an Avin kit in the mail and will be installing next week. Dash components are already disassembled waiting for the unit to arrive. Fingers crossed it's plug and play as advertised. I waivered back and forth but finally had it with the poor iPhone integration with the stock system. I'll post photos and a brief review at some point. I am expecting the screen to stick out a bit higher than the stock NAV housing.
I have seen reference to a V3 system with 4G coming this summer. I am optimistic that the V2 system will be enough for my needs - I only need WiFi.
$600 all-in seems very reasonable if it works well.
