Hello,

My radio regularly lose its DAB signal. Personally I think the signal is just fine because I can be in the same place on different days, and sometimes I have a signal and sometimes I don't.

Anyone with an opinion? I also think that when on FM radio it fails to re-tune to the strongest signal.


Thanks

This happens to me also. Buildings and other traffic cause this, signal strength, interference etc

I get your comment about same place different strengths, this isn’t the cars fault and could be caused by many factors including the weather.

The dab setup in the e89 is old and newer tech is better. I don’t get this issue on dab in my new c class for example.

I think what you are experiencing is typical for most DAB users. It's proven to be a major disappointment for many who have invested in DAB equipment expecting it to be better than FM for sound quality. I have a DAB radio in my ZED and also another car and the signal drops in and out quite often for no apparent reason. I also have a DAB radio in my home and it will only work in some rooms and reception of some stations can be ok on some days and non existent on others.

The Government has been encouraging people to switch over to DAB, warning that the FM service will be switched off but the date targeted for the switch over has been pushed back several times and currently I believe no date is set, although speculators put it around 2020. I hope the technology and coverage has been significantly improved by then!

DAB is an unreliable transmission method for moving vehicles, when it works its fine but it often doesnt and can be impacted by many things such as weather, trees, passing vehicles, the transmitter location and power etc which would explain why you get it sometimes and not other times. I have my AM channel selection programmed into one of the buttons so that when the inevitable happens and I lose DAB I can switch to the alternative AM alternative if there is one e.g. Radio 5 live, talksport.

I've never had a car with DAB, but I had a Mini with it fitted as a Courtesy Car and it must have lost the signal a dozen or so times in just a few miles!

That's when I decided I wasn't missing much.

There supposed to be an automatic change to FM when DAB drops - but it doesn’t work on BBC2.

Exactly
