I'm just looking at an update to my 1998 MV6 Omega, replacing with a 2002 MV6 with the Siemens Sat Nav Radio/CD/Computer etc. I notice that there are no buttons on the wiper control stalk like the older Omega, and I cannot seem to work out the control of the computer (selection of display of range/economy/sat nav etc) other than by buttons on the actual radio panel. I did get the unit to display a list of the key values by pressing the "O" button on the steering wheel, normally used to switch between tuner and CD (on my current car), but once the list was displayed, the only way to navigate it was to use the knobs on the radio - none of the steering wheel buttons did anything. Is this normal? It seems like removal of the stalk buttons is a funny way to go - they were convenient. There is no user manual with the car I'm looking at, so if someone could explain the operation of this model (I don't remember the model of the radio, but it is the Siemens one with 4xmultichanger in the dash, and sat nav) that would help. Also - is trafficmaster standard on later models. My current 98 MV6 has it, but I cannot see a trafficmaster button on this new one. I thought it was standard on higher spec models (this is an MV6) Rich
