2000 XKR Battery went dead so I charged it and after starting the car I had no power to the Nav or Radio. I checked all fuses and they were good but I did find two connectors right beside the battery that did not seem to go anywhere. Any ideas? Thanks Eddy

 

Try to disconnect the battery for a minute or so and then reconnect it.

The low voltage or the act of connecting/disconnecting the charger might have 'crashed' the radio and nav.

Those connectors you found are not used except for a power disconnect device when the car was shipped across the Atlantic.

 

Thank you for your reply and info. Eddy

 

Disconnected battery for 20 min hooked it up again and still no Radio or Nav. Any other hints? Thanks Eddy

 

Double check each of these fuses:

#9, #12 and #16 on the passenger side of the dashboard.

#16 in the trunk (boot)

 

Found it. Number 16 fuse on the pass side was no good. It looked great but tested bad on meter. I have it in front of me and it still looks perfect but amp meter shows no conductivity. Once again I thank all who helped this is a great site. Eddy
