i've a TOMTOM XL2 IQ satnav and my son has bought me the traffic adaptor. Only problem is... the traffic adaptor plugs into the same place on the satnav as the car charger.. so you can't really use the traffic adapter on long journeys as you would need the battery to be on charge. This seems one hell of a short-sighted piece of design... is there any way round this, like a 2-way adaptor that will plug into the ~TOMTOM? (there is only 1 input socket on the TOMTOM) I've looked for an adapter but can't find one..
