Just reviving an old thread
The iDrive with touch pad also add addtl modules to the system and from the first looks/info it won't be a simple retrofit via plug and play / sw update
Also the touch pad itself may not be for everyone as it seems to be fairly slow , you draw one letter and have to wait for it to be processed before you can draw the 2nd etc ...
