I hope yiou get it sorted.
It would be wrong to get rid of it just because of a stupid plastic clip. The door is a dealer issue and my Blue and Me failed the upgrade too. but then I didn't read all the instructins and took the USB stick out after only ten minutes so it's self inflicted in my case.
If I lost bluetooth and the back seat and the stereo I would still keep it - last week a boy racer in a wide wheeled corsa showed me he was faster than me, but when I got next to him at the lights the look on his girlfriends face told me she would rather be seen in the Alfa 159 I drive.
I can't face the thought of going back to looking over my shoulder in the carpark at a BMW, Audi or Volkswagon that blends in with all the others.
When loads of people point at your car and say 'like in James Bond' it's got to be worth some sort of shallow satisfaction, hasn't it ?
Now, the wipers (ahem !)
I never figured mine out too. I think you can defeat the automatic function or at least decrease it's sensitivity. I have mine set to auto and the right hand roller switch set as far forward as it goes. What position is that exactly ? Who cares ? what does it matter. The point is that sometimes in light rain they come on at full speed too and I just smile, safe in the knowledge that the system is working !
Smile and enjoy it, you'll feel better . If the problem is that your passengers make coments about it that's a different matter. Passengers should be subject to more thorough vetting procedures if you ask me.
