The concept of this item sounds great. Its so simple to fit. However does it work?
I have had two now. Both show the same fault - They work initially, then you drive 100 metres up the road and it comes up with an error message.
If you un plug it, set it up again it works for a minute or two - only to drop out again just when you thought you had got it working.
After two faulty units - Ive given up and gone back to the old Nokia 6210 which still works perfectly in the factory fitted Mercedes Command car kit.
If it worked reliably I think it would be great.
