My wifes 56 plate polo had developed very poor radio reception recently. RCD200 unit, completely standard.
It will sit on the drive for several minutes after initial start up with no issues but after a couple of miles on the move the reception across all FM and AM stations starts to become very poor.
Stopping, powering down and restarting achieves nothing.
Manual tuning also achieves nothing.
Going back to it a day later, will be the same, ok for first 5 mins then deteriorated to just about unlistenable after 10 mins or so.
Weve fitted a new stubby aerial, did not improve, removed the HU and checked all connections, all ok.
The CD is fine, speakers are fine, it turns on and off fine.
Is there a signal amp anywhere i can replace ??
Ive seen somewhere that the centre pin on the HU aerial output should have a voltage going back up to the stubby aerial, if this is correct what should the voltage be please ??
Any thoughts or assistance would be appreciated, she threatening to buy a new car !!!
