Fitted my trusty cheap dash cam the other day, not touched it since I cleared my px before getting the Roomster.

So last week started using the dash cam in the Roomster, since then started getting really poor radio reception. Today had my son in the car when the poor signal thing was happening so mentioned it to him. Removed the dash cam and signal back up again, so repositioned the suction mount and fitted camera and connected to power cable and the poor signal problem again. Seems to be only when the power cable is plugged in.

Has anyone else had similar issues?

DAB or FM? I had a Mini 0805 in my Octavia for a week and with it powered on you lost almost all DAB reception.

Standard Swing FM radio. Mine is a cheap chinese dash cam, £20 special off Fleabay.

Have you tried moving camera away from inside/ e.g. lengthening cable to get it as far away from radio to prove it's not  interference. Does it happen on all FM stations.

Possibility is that camera is transmitting FM signal ( and if affecting all stations ,it's most likely hitting the IF stages). We used to use this principle as cure for radio music wars in one factory. Three groups of workers outside the test bay decided to drown out each other. Remedy - set test sets to those stations, add an aerial and broadcast solid non modulated signal . Sets locked on to our strong signal with no modulation and went dead.

It only seems to happen when the charge cable is plugged into the camera, can have camera on without charge cable and it seems ok. Suspecting that the charge corcuit is emitting something perhaps. Tried moving the cables and camera well away from the radio and diversity aerial but it has had no effect at all.

Beginning to think it may be a replacement camera but worried that will be just as bad.

Was hoping to get a cheap dual camera system but this may be just as bad.

I have a 0805 in my Octavia, hard wired in, on/off with the key, works perfectly with no  reception lost on DAB or FM

Unshielded electronics in the power supply or the device itself.

 

I had the same bother with a cheapish camera I had at one point. The camera effectively blocked the radio signal.

I sent it back.

 

You could try another charger to see if it's the 12v plug or the camera that's putting out the em noise.

 

Otherwise it's probably a new camera.

Same problem with my Nextbase 202. Its definately the power unit radiating sh#t. Resolved by using the power unit from a scrap TomTom.

Well known in the comms trade that a lot of these plug in power units are rubbish despite having a CE mark.

Be wary about hardwiring without some knowledge, if your camera has a USB (mini/micro) power socket the it IS EXPECTING 5volts . Direct connexion , ie cutting off the plug and wiring to 12volt will cause it a short but spectacular life!

As you will have guessed from my forum name I've been into comms for a lot of years and this latest lot of mainly chinese stuff has caused no end of interference problems.

Haha that would be funny seeing what happens sticking 12v into it.

Funnily enough I have a little to do with radio.

Yeah been playing today and it does look like its the flipping charge cable. Didn't do it on the other car tho. Heho been looking for a usb cable to see if I can charge it from a usb charger.

Thanks for the replies guys
