It appears that only commerical users can get them.

good point. i wonder what one would do if that happened.
i guess u could just call and disable it.:dunno:

Behind the mirror? Do you mean the inside rear view mirror, or outside door-mounted mirrors?

I mean the inside miror, you can't see it unless you look real hard.

That is actually quite a smart, useful and inexpensive "mod"! :thumbup:

not entirely true. some cars require and external transponder.

Wonder if can one, if just have a BMW ?

honestly, i don't see y not. if they offer them for those
other makes, they should fit our BMW's. although, michelle
brought up a good point; theft.:dunno:

Someone had one on their X at the DC Meet...but I forget who it was.
