If by "convert" you mean "replace" then the answer is "yes, anything can be done with enough money".I was wondering if it was possible to convert the normal dash board to a Navigation dash board in a 2008 BMW 335i coupe?
If you had the dealer do it ....... oh, probably somewhere between $10,000 and $15,000. Could be higher though.How much would it be?
Here is a link to the Munich virtual plant tour.I have not seen video of the E90 being produced. Would you post the link, please?
It goes well beyond that too - which is one reason it would be so expensive. You have the bluetooth/phone, the ease of using the iDrive controller and let's not even get into all the settings you can change that you normally would have to pay the dealer to program. It's much more than a GPS which is why I love it. I still would NEVER try to retrofit it though.How often do you need Navi? If so get a Garmin and be done with it. The new ones even have Bluetooth. I take my Garmin out of glovebox maybe 1 time a month, and put on ash tray when I need it. If you use all the time, then get a mount for the side of the radio near glovebox.
And yes, the entire dash is one unit, assembled outside the factory, and install in factory in 1 piece, its like a plug n play.
