I have a 2009 CLK with factory fit Command NTG 2. I've added iPod interface in the glove compartment, a (hidden) Parrot interface for my Phone and a Pure Highway DAB radio hidden in the armrest. All is well but I'd like something a little more integrated and I've read that an upgrade to NTG 2.5 isn't possible. So, what double DIN aftermarket options are open to me? What I'd like is: 1. Sat Nav 2. Bluetooth Telephone 3. Ipod interface that can charge the latest iPhones 4. DAB radio 5. SD card interface 6. Steering wheel controls 7. I'd love cluster integration but realise this is a non-starter. Not bothered about DVD, TV or movie playback. Is this possible in a W209 CLK?
