Hi Jay Nine,
I have to say I have had similar problems talking to the connect center. I think a big problem is, as you say, that they don't have the needed language skill to talk to someone who is mainly thinking about driving. I have tried them 3 or 4 times, and the traffic info they gave me was next to useless - it appears as text on the screen, which if you are doing 70(?)Mph down a motorway is a bad thing to have to read. If like me you can't remember every junction on the M25, then you can look at a map - zoomed in so far that it is next to useless! By the time you have actually zoomed out, and figured where it is talking about you have got to the Jam! What would be great is for the system to automatically re-route you round problems.
But saying that everything else with the system is superb, the SatNav is now invaluable for me, as is the phone (for those who don't know to dial you press a button on the steering wheel, say "dial name", then the name you want to dial, the system repeats it back and you say "call" - your call is dialed. Wonderfull! It even gets simillar sounding names right 99% of the time.)
Plus you get the integration on the instrument-pod display: incoming caller name and number and the next direction instruction with a count down (great for picking which side road it wants you to take)
Currently I have a few problems with my unit, I was just wondering if anyone else had seen these: The radio reception is to say the least random; for example the drive into work I get a perfect signal all way, the drive back nothing at all - hiss and static for 50% and a week signal for the rest. The CD autochanger forgets what it was last playing sometimes when you turn the car off; sometimes it forgets about disc 1 in the changer (saying there is no disc in there!), the autochanger skips whenever you go over a bump, and even sometimes when you dont! I think these are odd-ball issues with mine, but I would be interested to be proved wrong!
But over all - it comes highly recomended!
PS. Trip B is available on all 147s (even if you don't have the CN+), it is a second trip computer. I think it automatically resets if the car has been turned of for half an hour, the main trip has been reset, or you reset it by hand. On all cars you can add it to the instrument pod display by finding the option in the display's menu (can't remember off hand), and then clicking through as for the main trip (it is at the end). On the CN+ cars turn the select wheel to the right on the trip screen (I think a click will then reset it). Otherwise on all cars get a Trip B screen up on the pod display and then hold the display-select button down for a few seconds. Its very handy for finding out when you left on this jorney etc.
