I'm having really bad signal issues with my Amundsen DAB radio, I took my 56 plate Octavia back to the dealer at the end of Dec last year and they found it needed an update, so they did that and now on my daily commute over the peak district it's dropping signal all over the place, dab goes off and FM comes on then that drops out too. I'm getting pretty fed up with it tbh.

 

My previous car a golf GTs on a 09 plate was perfect all the way there and back, never loosing signal once, even when I swapped the stock aerial for a stubby antenna.

 

I have a dash cam with a rear camera, so I have ordered some chokes as mentioned in another thread, I'm hoping that cures the problem.

 

Any ideas or suggestions, please post. 

I live in the sticks in Northumberland, and don't have any problems..Dab Fab :-)

Does it work without the dash cam plugged in?

Maybe its interfering.

Seldom have a problem with DAB, but I guess it depends on the signal in your area.

My 13 plate VRS had terrible trouble with DAB, signal would drop out frequently and occasionally it would sound like the music/presenter is underwater!

 

Dealership tried a software update and replacing some components but never got to the bottom of it. My 16 plate is perfect though!

Pretty much perfect on my car from day one, only gets garbled in a few places locally, usually steep hills running up/down near a valley, works pretty well across most of Central Scotland.

This problem is usually the power supply for the dashcam. Cheaply-made power supplies reduce the vehicle 12v to the usb 5v by rapid switching. This generates radio waves that swamp the weak DAB signals. It does not matter if the dashcam is switched on or not, but when the power supply is switched on, or plugged into the car. It can be cured by fitting a better design of power supply. After trying several, I found that the power supply from my old TomTom Go730 was excellent, no DAB interference at all. I have now fitted this in 2 cars with the same result. You can get TomTom power supplies readily, ensuring that it is a genuine TomTom one, not a copy. There may well be other power supplies that are as effective.

Thank you all for the replies, apologies for my lateness in coming back but I seem to have got to the bottom of the problem. I bought a box of 10 off ferrite core clip on blocks, I have added 2 near the positive connection by the fuse board on the supply to the multi socket adapter, then I have 2 on the power supply for the dash cam and one on my mobile phone charger.

 

I'd read about these in another thread on here.

 

I'm now getting almost no interference, but I'll see if I still get signal drop off tomorrow morning when I go back to work, I've been off since last Fri afternoon.

Added detail.

Peak District DAB is now pretty good. Only in the odd deep tree lined valley does it revert to FM. Also  home reception in NE Derbyshire is so good the telescopic aerial in our new DAB Blaupunkt kitchen radio is not deployed.

Hi gregoir,

 

All was good this morning, the only bit where it almost dropped off was as you go through the last bit of the tree lined valley above Stoney Middleton, just below Housley. So glad I joined the forum.

The stereo issues had been driving me crazy.

I have LED indicator bulbs, when I indicate the DAB loses signal :-)

It was rubbish before the bulbs TBH, constantly struggles to find signal / drops out.

 

I just don't bother using it
