I have a 2011 f25 x3 with full nav. Would I be able to put the NBT (id5, not evo) unit in my car without having to do the harness upgrades like I would have to if I had no navigation?
I retro fit the nbt evo in my 2007 e90 335i and that was a HUGE ordeal in comparison to what I'm hearing everyone here say.
