It is 005 in the link, to test unplug the lead that goes to the car radio and touch a long piece of wire to the center pin while tuned to a weak station, then do the same on the antenna wire going in.

Many Thanks

When i bought the car they had removed the phone system and i think it had a command system, i thought the aerial was in the back window but did notice a gromet in the roof at the rear which i thought was not very mb. lol thank you for the picture but im still a bit non for the wiser as to which system i have roof or window. will have a check in a bit. many thanks Malcolm

The antenna bit is the wire in the glass on the rear door, this goes to the amp in the c panel corner and then on to the radio.

The hole in the roof was for the phone and nothing to do with the radio

If someone has been removing things in the C pillar area, then it is very easy to break the thin center wire on the antenna cables

This is why I said tune to a weak station and touch the center pin on the plugs with a piece of wire just hanging out of the car, if the radio springs to life then you can find where the fault is

Just a quick thank you, the wire had come of the booster module thingy, clipped it back on radio works perfect now. thanks Malcolm

Hi

Are these connectors push-on, screw-on or clip-on? I am wondering how the wire came off the booster and what could have caused it?

Most are a push fit,,if not right in then the center pin may not be making contact,,some cars use the wisiclik plugs

Hi Malcolm

This thought occurred to my indie and the Hi-Fi Specialist. The pin, coax adapter and antenna plug & cable were found to be OK when my tuner was tested.

Just a thought, but would the MLs use a similar electronic antenna system to that employed in my C class?

All MBs from the 202 on use the same system
