I have a fully working AVN2 head unit for sale - now on eBay - originally from my 25th Anniversary Edition (now sold) which I had replaced with a Pioneer unit. Prior to that, I had updated the firmware to the latest Alpine version at the time (BDAG104A) as described elsewhere on this site. I also upgraded the maps to the 2020 version. It comes with the original wiring loom and GPS receiver etc.
Price and details please as per the forum rules
