Comand 2.0 modern replacement?

[soups74]

I have a mercedes clk 2003 model, with a factory fitted comand 2.0 unit. The unit features a sat-nav and tv which the tv worked fine in analogue until the digital switchover. Therefore, now doesn't work! Rather than upgrade the current unit to install a digital receiver for tv, I'm wondering whether to update the whole unit for a more recent one. Does anyone know what unit may replace the comand 2.0 in the same size fascia or is anybody selling something more updated than my current one? I'm interested in any ideas, anyone has. Thanks.
