hi all i have a mondeo mk 4 2007 1.8 tdci . i had a problem with a previous radio , so i changed it for another used radio same model the 6000 , on both radios i have had the same problem i.e sometimes it switches on and off on its own, the display does not always go out after i have locked the car, sometimes the display loses all the information and just shows lines where the info should be then it will come back again, also the controls on the stalk to operate the phone etc does not work. this has happened on both the radios so i find it hard to be a coincident. with the first radio all was working properly then it just started doing all of the above , so guessing its not the radio,s that are at fault, any help appreciated many thanks chris
