Sat nav keeps losing its gps signal, does anybody know why please?

Question

the car is a peugot 406, it worked fine in my last car which was a older passat

Answer 1

An external attena may help.  Big buildings in the city or mountains will block the signal

Answer 2

get antenna checked

Answer 3

What kind of car are you using it in? It may well have a "solar" screen. This is a coating applied to the glass to cut down  U.V rays and heat. This can shield the signal.

A heated front screen shouldn't interfere with the signal though.

Answer 4

Is it behind a heated or heat reflective screen? If so an external antenna may be required

Answer 5

On my system the sensor links to the display (PDA) via bluetooth.  This means I could use it without messy cables - just rely on the sensor and PDA batteries.  However,   I've found that if I don't use a cable then the system is less reliable.  I suspect that this is because the battery voltage gets too low for the sensor to send a good signal to the PDA.

Answer 6

Tall buildings, tunnels, bridges, trees, hills, "metallised" windscreen, anything that obstructs the signal.  Try an external aerial.

Answer 7

Do you have a big stereo system?

Did you ad any up grads to your engine?

If not most likely a short or lose wire.  Or the hole dam thing.
