Hi has anyone had the same fault as me, The radio is on then hit a bump in the road and radio goes off, press the volume button twice and radio comes back on sometimes and sometimes it will not come back on for ages, Hope someone can help as it is so annoying.

Do you have Sat Nav with screen or the Business radio?

First I would check the simple things like all connections and plugs. If you have Nav all the main connections are in the boot under the floor and the spare wheel and in the left side cubby.

The Business radio connectors are behind the radio in the dash, as a bump causes it I would suspect a loose connection.

Mine does the same.. its just the connections in the wires at the back give them a wiggle

Hi Thanks for that i will give the wires in the boot a coat of looking over as i have put another CD exchanger in and on the screen it comes up cd but nothing plays so the trouble could be in the same area, I will give it a try and keep you posted thanks.
