Mk4 mondeo - Dash cam mw radio interference - S40 Man
I bought a cheap dash cam recently (£16) from a service station. It works ok, images not too bad for the price. My post is about radio interference on mw. On CD or FM or Bluetooth its fine but in mw I get so bad crackling and hiss I can't have both on at the same time. I have aftermarket Alpine head unit.

Anyone have similar problems or a possible solution?

Yes,seems to be a problem on the cheap models.it is interference from the plug in power adapter.

Hello,

Yes I thought it was to do with the power supply. It goes in the 12v accessory power socket. I will investigate the capacitor idea in another post .

Thanks

Assume interference is only noticed when dash cam is active.

0.1 micro farad capacitor between power supply of dash cam and earth of vehicle will solve this.
