UKPassats

Hi all. Looking for some help - I just bought a 2017 Passat Estate from a company. For some reason the company policy is to disconnect the radio - the infotainment system works but the radio doesn't get any reception. Does anyone have any idea what the simplest way would be for someone to do this? The company doesn't know how it was done but said it was policy for all their cars.

I'm guessing it would be to disconnect from behind the head unit in the glove box but thought I'd check here.

Many thanks.

Neil
