Can anyone help i have a tom tom one xl works perfect outside car ,but when i turn ignition on i keep on losing satellite signal,i have a renault clio car van, and have updated software also to latest so i know its not tomtom but some sort of earth or something affecting signal but cant work this out ?has anyone had a similar problem or knows anything about earthing maybe? not sure ?

have checked all earth points straps etc,not Radio Frequency Resistor,the vehicle is not new 04 plate,renault clio car van sl15 dci 65 1400cc diesel,so no spark pulgs,the tom tom is working perfect outside inside vehicle until ignition is switched on?? yes it did belong to a company highway surfacing ltd so i dont know about tracking device but something is infereing with signal when ignition is switched on?? real puzzle ??

Does it work inside the car with the ignition off ?

The heat reflecting windscreens on modern cars can block GPS signals, but as yours is fairly new (I think :think:) then I would expect this to have the newer GPS chipset in it (Sirfstar III or something) that overcomes this issue.

:confused:
