Hello all! Just bought a 2011 E220 cabriolet with the Audio 20 music system without nav and whilst taking the radio out to see where I can get a decent ignition live feed to power my dashcam, noticed 2 antenna feeds going into be back of the unit, one is a double fakra which I'm assuming is the fm/am signal and the other is a single blue fakra. The car itself has a sharkfin on the boot lid and also what looks like an antenna built into the front screen. Thanks for reading this far if you're still with me, so which is which???

FM/AM is in the windscreen definitely, there are two amplifiers one in each windscreen pillar, sharks fin is GPS ?? and or telephone.

Can't be GPS as I've not got nav, got to be Bluetooth then.
