There are two parts that are required to use the COMAND screen for TV, video, video games, dvds, etc.<br>
<br>
Part 1: The Mercedes bit: COMAND needs to be switched into TV mode. This is no problem with European models. The software is fully aware of the existence of a TV module and if there is one built in, you can switch to it. In some cases, when for whatever reason COMAND has been preconfigured as not having a TV module (an unnecessary preconfiguration, as it senses the connected modules), an MB-technician has to enable TV with Stardiagnose. I have heard (but it never has been confirmed) that US COMANDs have a different software loaded, where you can not switch into TV mode. If this was true, then you would either have to buy a European COMAND unit or load the European firmware (your MB dealer shoud be able to do that).<br>
<br>
Part 2: The TV module: There is an official TV module from MB in Europe. It only supports PAL TV systems (and not the US NTSC system). Apart from offering TV, it also offers two video connections where you can connect ANY video source as long as it is composite video. This could be from a video camera, a video game, a portable dvd player, a built in (car) dvd player or a laptop. As the video source is composite video, the quality is not as good as on a digital TV, but we are talking about a small 5' screen, so who cares. Now for the US market (or for whoever has a COMAND system without the TV module - as retrofitting it costs a fortune). There is a multimedia connection kit (I posted a picture in the audio forum) for 399 Euros that offers a composite video connection. To this you can again connect ANY video source such as a (NTSC) TV receiver, a dvd player, etc.<br>
<br>
As I never was interested in TV reception, but in dvds, I connected a small DVD/MP3 player to it. This gives me the ability to watch dvds or listen to music when I drive. By the way, any MB dealer with Stardiagnose CAN switch the 5 MPH limit off. Some of them will NOT WANT to do it, others will want you to sign a non liability document.<br>
