Nik .. Have a look for interference sources on the GPS .. It sounds odd I
know but its happened to me. A few months ago I bought a cheap Ebay
Bluetooth Handsfree kit that uses a small transmitter on the FM broadcast
band and plugs into the cigarette lighter socket. I found that running the
thing at around 88Mhz caused it to go spurious so much that it actually
wiped out any GPS receiver within 15 feet.
Seriously bad stuff. It had me swapping GPS units franticly for a while to
no avail. When I use that Bluetooth kit its usually in a loaned car and I
remember to run it well above 88MHZ
