Digital TV - "no signal"

Hi guys, I've purchased a G30 540i xDrive recently. It's two years old and already without any warranty so before I visit our local overpriced and usually useless authorized BMW dealer I'd like to know your opinion.

The car has a (digital) TV tuner - is it DVB-T or DVB-T2? I couldn't find the specification anywhere. Anyway, it doesn't work - when it searches for available programs it does find about 60+ TV stations but doesn't list the station titles and ends up with a "no signal" fault. What's wrong? If the tuner didn't work it wouldn't find the 30+ TV stations, right?

(The car is German and when I was driving it in Germany one TV station did work for a while - ZDF HD. After some time I wasn't able to tune it anymore. When I arrived in my country (Czech Republic) nothing worked. (I tried to switch the area between "Automatic" and "Central Europe" but got the same result in both cases.

I'm pretty sure our country provides both DVB-T and DVB-T2 broadcast so that shouldn't be a problem. Also many stations are found. So why do I get the "no signal" message? Is there something I might have overlooked or something I might be doing wrong - or is the authorized dealer the only place where they could solve it?

Hi Mr. Scully. Have you been able to solve your situation? I've exactly the same. Recently bought a used BMW in Germany where the TV (DVB-T2) functionality was working. Back home in The Netherlands nothing is working anymore. During a scan I can see the system finds TV and Radio stations, but after the scan the system ends up with a "no signal" message and no channels in the list.

Not yet :-( I think the first step should be finding out whether G30 has a DVB-T or DVB-T2 tuner (both are digital). Then the second step is finding out which TV stations in our countries are available for free. And a third step - to find out if it's possible to purchase a prepaid card/module for catching signal of paid TV stations.

In any case it's good to hear I'm not the only one - clearly the TV tuner isn't broken, it's just an issue with lack or free TV stations? I'm willing to pay for a CI+ module to access more channels but nobody seems to want my money

A Ziggo card will not work. The only provider in The Netherlands that provides a DVB-signal is KPN with Digitenne. A couple of weeks a go KPN switched off DVB-T and is only offering DVB-T2. With the change to DVB-T2 KPN is also no longer offering Smartcards for a CI+ Module anymore. So in The Netherlands we can only watch the Free-to-Air channels in our BMWs

The FTA channels are: NPO 1, NPO 2, NPO 3 and the local TV stations (check: https://www.digitenne.nl/blog/gratis-tv-kijken/).

According to the official BMW parts website (https://www.realoem.com/bmw/enUS/sho...diagId=65_2640) the TV module is always a DVB-T2 version (I've selected the earliest available G30 540i xDrive of 11-2015).

Thanks, that's good to know.

According to my research most of Czech TV stations are currently broadcasting (for free) in both DVB-T and DVB-T2 format in the same time (DVB-T will be switched off later this year). So it's still a mystery why I'm not able to watch the free programmes.

(It's also weird that the BMW tuner does find plenty of stations - without names - but doesn't offer them).

Should I start searching for some local CI+ module/card/whatever? That might be the solution? (But we have only providers offering cards for DVB/S/S2, the terrestrial broadcast is free).

edit: for the Czech broadcast the tuner must be able to tune in the UHF "zone" (channels 21-59, channel width 8MHz) and it must be able to devoce HEVC. I have absolutely no idea whether the BMW tuner is compatible with that but I assume it should be!

A fellow owner of BMW (not sure which model or iDrive version) suggested that his TV tuner started working after he performed a factory reset in iDrive - apparently a menu item hidden somwhere outside the standard menu, somewhere below "teletext" (?). I don't remember any such setting but surely a factory reset can't make things worse so I will try to find it.

That's really weird. Seriously nobody's TV in G30 is working properly? Or does it at least work in the car's country of origin?

I noticed that the software/firmware in all my "head units" is from 2017 (and some cannot be upgraded due to some unknown ethernet/flexray communication faults) so I'm going to try to upgrade all the (31?) head units to the latest software and we will see. (Not that I could do it myself but I have friends who are experts and might be able to).
