I have a Navman S30 (serial number BC889MO9886) which will not find a satellite. It will find its maps, accept addresses and postcodes but refuses to find a signal, giving me the message it cannot find a GPS Signal. I've endlessly reset it, pointed it at the sky on sunny/cloudless days for a half hour at a stretch. Nothing. It hasn't had a lot of use. Is it kaput?
