I-drive / Navigation Professional Retrofit for the E90

…as performed by Booster4075

With support from the members of the e90post.com forum / Navigation retrofit thread at:

http://www.e90post.com/forums/showthread.php?t=131416

Document revision 1.3 – 10/22/08

_____________________________________________________________________________________

Disclaimer: This retrofit should only be done when all other options are exhausted (i.e. Buying another car,

etc…) It is assumed that doing this retrofit would void the warranty on related systems and this is not at all

endorsed, supported, or otherwise suggested to do on your BMW e90. I wouldn’t recommend even thinking

about doing this retrofit until fully researching this effort. For most people, you really are better off buying

another car and leaving this retrofit to the die-hards. Know your limitations and those of who you entrust to

tamper with your vehicle. This retrofit is not for the faint of heart...merely changing hardware is only half the

battle. If you are even contemplating doing this retrofit, secure someone, somewhere, who has the equipment

and know-how to get this programmed FIRST, before buying or changing anything. As these cars are literal

technological masterpieces, it requires strong technical measures to enable these cars to recognize and use

even this OEM hardware. If BMW had made a (authorized) retrofit, this would be as simple as going down to

the local dealer and having them “add” the software to the car. Unfortunately, there is no such "retrofit"

software package and dealership service departments have no idea how to do this and most won’t want to

help even if you throw money/shop labor at it. (I’ve thrown money towards dealership labor to “try” – it’s a

waste of your hard-earned cash at $175/hr to get zero results.) It is likely that there is a “hacker” technician or

two at each shop who does know how change a vehicle order and "make things work", but isn't "allowed" to

do it for customer cars. This is nothing like the old days of putting in a car stereo and amp and having it work

out of the box. Some independent shops have talented technicians with up-to-date knowledge and

equipment that may be able to help. All of that being said, I have no regrets in doing this retrofit and have

learned a lot along the way. If you have any doubts, do what several dozen people told me…buy a car with

Navigation already installed.

It should be noted that my car came already equipped with voice control/recognition, Logic 7 audio, BMW

assist and was Bluetooth equipped from the factory. Your car may or may not be similarly equipped and may

need additional harnesses, parts, and/or have other issues during this retrofit. You can also refer to the BMW

Accessory installation documentation for the Business-to-Professional navigation system retrofit (SA609), p/n:

65900415350 / 65836976392. This documentation may aid you to fill in the gaps if your car is not similarly

equipped (i.e. adding a microphone, etc…) Some of these individual retrofit parts are still available also – some

are not.

"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.

If you are considering this retrofit, make sure to carefully consult the BMW WDS for your exact car. I utilized the BMW TIS fo...
