So I dropped my Z4 off yesterday at a reputable Viper alarm installer to have an alarm put in. They called this morning and said they've exhausted their resources and spent 3 hours trying to get the alarm in, but are giving up. None of the wires that are supposed to control the alarm functions in the car do what they're supposed to, and their Viper technical support (over the phone) has run out of ideas. My car is prewired for an alarm, but that may only help with installation of an OEM alarm. Has anyone had a similar problem? Am I limited to only buying an OEM BMW alarm? This is certainly a surprise to me. Help!
This is not a good solution for a working person. Thanks BMW!
