The E85 at least doesn't have an aerial in the rear window. They have the rear quarter mounted one (stubby on mine) and a line type one suspended from the body behind the rear bumper. They are both amplified, and there is a "diversity" switcher which optimises reception between the two. The "stubby" is used used for AM/FM, and the line aerial behind the bumper for FM only.Number5 wrote:"Compatible for all vehicles with Navigation, Bluetooth, TV, Etc" - Thats all nonsense !!
My understanding was that the Stubby/Whippy is only the AM aerial anyway.
The FM Aerial is built into the rear windscreen
The TV Aerial is on the rear left quarter, under the rear lights and runs along behind the bumper
The SatNav aerial is tucked up above the rear view mirror, behind the Courtesy light
The Bluetooth aerial is behind the dash, nearest the driver. Why would you put it outside the car ?
