Tom Tom Car mount

Hi

I have just purchased Navigator 5 for my IPAQ 5550 along with the car mount kit.

I have tried everyway I can to get the suction cup to hold for more than 5 minutes without falling off either te windscreen or the special cup (Disk).

Can anyone suggest a way to make it stay on permanently please.

The IPAQ 5550 is quite heavy and the weight is considerably far from the suction cup, but it will still not stay on without the IPAQ fitted!

Thanks for your suggestions.

Ian

have you cleaned the glass with an alcohol based substance?
