They also talk about unlock codes and SIM cards, so I'm assuming that at least their unit will be GSM and maybe you can use your own SIM card.
The phone options are just like the rest of mercedes fleet with the UHI options and the different phone cradles. If bluethooth is available, probably is but the traditional format is there too.
You can translate with google until you view the pdf version of the brochures.
