[woodsy1123]

hi all new member alert lol

 

i have a long wheel base transit and the stereo keeps cutting in and out while driving when i turn left it gets worse or cuts out completely and when i turn right it gets better or works fine 

 

i have removed the original head unit and tried an after market head unit but that did the same i have tried dis connecting the steering controls but that diddnt make any difference

 

theres no breaks in any wires thats visible i justhavent a clue how to sort this and its not anywhere as a common fault ect 

 

any help very much apreciated
