Omega Elite Sat Nav

Can someone shed any light on this.

1997 Elite with the original Phillips Carin Sat Nav. For the first half hour
it's all over the place but after that fine. It's only when it's acquired
enough satellite signals that it gets to work, and it works fine after that.
It seems not to be able to acquire the satellite signals fast enough, and
this can take up to half an hour.

Any suggestions?

try staying in the same place with out moving for 10 minutes... it may be
that it needs to accuire the satellites if the bettery has been disconnected
for some time.

 

The battery hasn't been disconnected recently but following on from you
reply (many thanks btw) could it be the case that I need a new battery? When
I have all heated seats on, rear window etc. the battery light on the dash
is very slightly illuminated meaning battery or I suppose alternator. The
car is fine apart from this Sat Nav issue but it's getting on now and I
suppose I don't grudge it a new battery if needs be. Will this help you
reckon? Or is there a more sinister problem with the battery light coming
on, albeit dimly. I remember something similar happening with a V6 Calibra a
good few years ago now. The alternator was replaced but the same fault
recurred. I sold it not long after that so didn't pursue the matter.

Any help, most appreciated. It's driving me nuts.
