A guy has upgraded his PX2 Ranger Sync 2 to Sync 3. Was plug and play minus the GPS antenna or the digital radio antenna (can't remember which one sorry).
Sync 3 in my Ranger has been excellent, its alot quicker then Sync 2 and the Apple Car Play feature is very handy.
By that token, a Sync 3 from a tuk tuk (ranger) should fit into the falcon, shouldn't it ?
