Mercedes V Klasse Radio Reception Issue

Alright so, I've got this Mercedes V Klasse, build year 2013, gasoline engine, around 52834 km on the clock. Lately the car radio reception has been absolutely dire. Getting a 'no signal' error on the infotainment screen sometimes, other times the whole audio system just dies. Took it to get the error memory read and it's throwing some code related to the antenna. Suspect it's a defective antenna. Anyone else had similar issues with poor signal? Thinking it might be an antenna booster or something related to the vehicle electronics causing static noise. What are your thoughts before I shell out 255€?

Hmm, that's strange. I had some car radio issues once, turned out to be a loose connection. Have you checked the antenna cable connection at the back of the radio unit? Is it properly seated? Also, does it only happen in certain areas, or is it consistent everywhere?

Thanks, I will check the connections but I am not sure where to find this antenna cable, is it easy to access and do I need special tooling to check the connection? Is there something special to look for?

Accessing the cable can be tricky depending on your car's setup, might need some trim removal tools to avoid damaging anything. If you are uneasy about it, I'd suggest taking it to a workshop rather than risk messing with vehicle electronics. They should be able to diagnose the antenna issue quickly.

Right, thanks for the advice. Ended up taking it to the workshop. They confirmed it was a defective antenna and replaced it. Cost me 255€ as expected. Radio reception is perfect now. Problem solved.
