Would using a GPS antenna make any difference to the traffic reception?
I use a works van and cant make any connections permanant as i only have the van for 18 month then i get a new one.

Any ideas out there?

cheers

A GPS aerial will only aid GPS reception as it is designed to operate around the 1,5 GHz the GTM21 is an FM band receiver operating at 88 to 108 MHz if you want to improve reception of the GTM for traffic information I would look at using something like a Mini-Scan or Sky-Scan mag mount aerial from Maplins as these operate down to around the correct frequency coverage (Sky-Scan is a better choice, but it costs more and looks very strange when fitted to a vehicle) - Mike
