It is SO-O-O-O frustrating trying to keep the old BMW electronics up to date. Over 2 yrs ago I finally pulled the trigger and had my local Alpine dealer yank the old nav Mk4 out and install an Alpine INA-W900BT (latest version is a INA-W928BT with an 8" screen vs my 7"). Best thing I ever did. Expensive! Old BMW plugs need to be replaced with new wiring. But now it is sweet to have modern electronics vs playing catch up (which you never do).
