GPS reciever can be mounted in the little rectangle in front window, but i think it is better to put it on the ledge of the rear side window, it sits nicely there and gets good reception.
I can do the lot for £245+ insured postage. Usually around £8 next day delivery iirc.
Will also supply backup disc of software for the people who have already purchased tomtom 5.
I have everything here for one visor, except I dont have the pda or sd card.
I could do this for £100. This will include all wiring, a gps reciever, the sunvisor, sticky velcro and a cd with instructions and software.
If enough people want them I can order it all in bulk and do it slightly cheaper, with or without the pda.
All that is required to fit is normal tools, bit of string, soldering iron and insualtion tape. Only five wires need to be soldered.
