2005 330ci Convertible - issues!

Hello all-



This is my first post and I am the recent purchaser of a 2005 330ci Convertible. I am from the Minneapolis area and made the mistake of buying a car on eBay from Chicago. Long story short, this has been a nightmare. But enough of my complaining...



My main issue right now is that the previous owner - for some unknown reason - removed the rearview mirror from the car. Now not only does it not stay attached to the windshield, but neither of the key fobs lock or unlock the car - let alone release the trunk or operate the top.



I brought it in to a "luxury" dealer today (non BMW) and after $170 in labor, I am still left with no remote lock/unlock. I have tried the reset items I have found on here (disconnect battery, move key to position II - remove - hold down unlock while pressing lock three times) with no luck.



Question is, is my issue in the mirror itself (compass works and garage door buttons work), or do I have a GM5 module issue? If it is a mirror issue, can I replace the mirror and my key fobs should still work?



Thanks!!
