orange spv m700

[Guest crazydoc]

Hi

Can anyone help me? Recently upggraded to orange SPV m700. Want to use it as GPS with TOMTOM 6. I have a car with an athermic windscreen (heat reflective windscreen) so hindering satellite signal. According to manual it suggests using an external GPS antenna. Carphone warehouse and orange have been no help and don't sell any antennas. There are plenty on the internet but I don't know what sort of connector fits the phone ie MCX or MMCX type or other. Any ideas out there ;)
