From my observations in UK I can see that in the case of DTV the transmitted power levels are significantly different between the national DAB TV stations (BBC) and commercial/independent providers. 20KW to 9KW. DTV on commercial stations often drops over the digital cliff...pixalation and black out.

The DAB radio transmitted power levels in UK I cannot find but suspect its the same kind of ratio. With the BBC crap hanging in there most of the time and commercial drop out at the turn of a corner or down a gradient....a bit. ICE screen goes dumb as the ICE processor tries to recover above signal level threshold...no message on screen, just dead view. Changing station is usually an awkward event for most people I'd say....very unresponsive ICE system.

Its all about money...of course!

On DTV there are problems with adjacent channel interference by the mobile phone system and requiring in some regions (mine) the insertion of UHF notch filter.

There's probably nowhere with more DAB signals than my area!

For info..DAB problems:

I asked my son who has a 4 yr old Mercedes C63 what his DAB performance was like in UK. He told me 2 years ago that Mercedes were applying a software upgrade that apart from anything else would ensure DAB+ would work ok. His DAB radio performance then was junk he said.

So after 2 years more servicing from then he tells me his DAB radio in UK (London) is crap but works well in Germany when he goes there a couple of times per year.

I have a view on this and it starts around technical specifications and standards. Fortunately for me I do not use DAB or FM for that matter, primarily because its full of advertising crap + general propaganda (as is DTV).

The central cutomer support people finally admitted to me (after nearly a year of trying to get an answer) that there was a big problem and that they were working with their suppliers (Bosch?) to get a reliable software fix.

I was advised to get D554 installed, but told that it might not resolve the issue completely, and that a lter update (when available) might be needed

The issue can't be down to just reduced power DAB transmissions. When it fails, input from the AUX socket/cable (e.g. iPhone playing music) also fails. As does FM and LW.

And it certainly doesn't explain the unit constantly giving up the ghost and re-booting (as mine does with increasing frequency). That's a major software bug.
