Different types of sat nav fittings I got a Garmin nuvi 2559 lm sat nav for Christmas, but am finding it very awkward fitting it to the windscreen and it also blocks a lot of my vision. Has anyone any tips or have tried the Garmin Universal Friction Mount or found a dashboard mount that works. I have just seen that there is something called an air vent fitting - which as the name suggests fits on to the air vent. Has anybody tried them? Thanks Liz
