I have lost the **** to control my gps... Damn! Anyway, a new one from bmw is like (you have to buy the entire trim kit)$250!!! Does anyone have a clever idea on a replacement? Looks just like the volume **** on the radio... Kinda. Also, has anyone seen anybody replace the gps screen with something like a small android tablet? Looks like a Samsung Galaxy tab would be a nice mod. Would be nice to be able to use Google navigation rather than the crappy mini nav. Thanks in advance!
