Success a last!!
Thanks to Andrew.
I downloaded the driver from
WWW.roadcom.co.uk as he suggested.
However, I had to get into device manager and right click on 'Windows CE USB devices' and upgrade the driver manually from the C\RC400Driver folder.
And it worked!
Active sync appeared as if by magic with the RAC210 connected.
I was then able to download the free safety camera update from the 'Route 66' website and load it into the satnav - fantastic.
I don't wish to seem ungenerous, but wouldn't it have been a good idea to have included this driver on the disk supplied with the RAC210 satnav in the first place?
Its a bit like buying a motor car and finding that you have to send away for a steering wheel to make it turn corners!
Thank you once again one and all.
