It's just BMW marketing to entice you to purchase their over priced cellular phone.
Personally I'd suggest a portable hand held phone versus the car mounted phone simply because you can take it with you.
Car mounted phones, IMO, are going the way of VCRs (to be phased out).
A portable cellular phone does not have the electrical output power necessary to adversely affect your vehicle's electrical system. You'll be fine.
