Satellite Radio Antena Location

Hi,

Does anyone know where the antenna is mounted for on the 645Ci Coupe?
My previous 545i had the shark fin, but the 6 doesn’t.

Thanks

I've been told it's in the rear bumper.

Jeez, u must really want to know, third similar post in three different forums.

Same answer in all three. Two multi-band (frequency) antennae tucked under trunk lid. One just each side of centerline. Two connections to one, three to the other. Each one is a different part number. Although parts list shows an antenna amplifier my '05 does not have one. I suspect it was for TDMA phones and/or CTP9000 phone. The trunk is non-metallic composite material.
