Satnav woes

The plot thickens on the Blackberry satnav failing to charge from the 12v outlet. Tests show that current is reaching the connector to the handset but the charge symbol does not appear. Another PDA does show charging. The Blackberry does show the symbol and charges from the mains. The plug into the handset or the handset socket look to be main suspects - so the search is on for a new cable and connector.
