Of course all 07 & 08 owners want to know if the new idrive can be retrofitted into their existing vehicles. I'm sure if there's a will, there's a way. Heck if you can retrofit nav from scratch, I'm sure you can upgrade - although it will probably cost as much as a whole new nav install.

So rather than speculate if it's possible, we need to talk to some 3 series owners that already have the new idrive and see how the guts are different from the previous 3 series.

Any 3 owners here??
