Update: Today I popped into a VX dealer in town and asked the question. The service manager (although trying to be very helpful) said that the Diamond version does not have BC function. I asked why the button was on the panel then, and he replied that it's the same panel used on the Exclusiv, which DOES have BC function, including engine temperature. This doesn't make sense to me - why put a button in a vehicle which is a higher spec, but not give it functionality?
I then asked if I could have the computer upgraded. He went away and spoke to someone and came back and told me that none of the mechanics and technicians at that dealership had ever done one, but it was possible as far as he knew. I would "have to find a VX dealer that knew about it and could do it".
When I asked how I could tell the engine temperature, he said "you can't, you'll have to wait for a warning light to come on" WTF?? That's disgusting customer service from a VX dealership and also disgusting functionality from the idiots who decided that a high spec car doesn't need the driver to know the engine temperature, the distance to empty, the mpg etc. The engine temperature is very important to me as I tow a lot (the reason for buying the vehicle) and it's always a problem with overheating with any vehicle, particularly on long steep hills. If I have to wait until a warning light comes on, the damage could already be done. Ridiculous.
On a plus point, apparently the cruise control IS plug and play and it is a minor job that's fairly cheap...........................
No luck with the USB function yet.
