This mounting solution is vehicle specific according to year, make and model.  They are a must-have for today's gadgets gurus.  They can be used for mounting satellite radios, like Sirius or XM, or you can use them for mounting GPS units and cellular telephone hands-free kits. These mounting solutions can be very important in assisting in the installation process because in many cases the vehicle can be returned back to a like-new condition with no evidence of any installation ever in that vehicle.  A plus for leased vehicles or for the person who likes the latest aftermarket gadgets but does not want to permanently scar the vehicle's dash.  The mounts are designed to be installed with regard to air-bag deployment and the passenger's safety.
