If you are on the fence about this go ahead, Had one installed in my GL63 and it works great. Was considering the cell add on but not needed. Good range with the factory key.

Cost (device and install)?

$990 installed. Can't give you the breakdown. It is a plug in unit somewhere in the rear of the car. You have on off switch that my installer put under the dash.

Thanks. So when you turn vehicle on with remote start does it start the ac/heat settings you had going when you last got out (ie can one use this to start the car from inside the house so it can warm up inside on a cold day?).

Yes. Here is Texas I use it to turn the AC on before I leave the office on the 100+ degree days.
