couple of questions after w203 radio swap

[mad4amanda]

Hi guys fitted my Becker indianapolis pro today all working ok just a couple of questions though:

1. on the back of the old audio 10 there was the normal iso aerial which fitted the Becker immediately and a small under 5mm diameter sincle black lead that was thick like a coax type lead any ideas what it was for ? Audio reception seams ok.
2. Is there an interface for the steering wheel volume controls that will work with the Becker unit I assume they were the 3rd plug with just 2 wires in it that I have left out at the moment?

it would be good to keep the wheel buttons but not essential. and Im curious as to the second thick black lead with a small push in connector.
many thanks
steve

Car must have came with APS 30 which was swapped to Audio 10 at some point and the leftover cable is the GPS antenna.

Mercedes C W203 ( 04) CAN Steering Control Interface | eBay you will need to check if it works with Becker units.
