I've just wired up my dash camera normal route across top of s creen and down the pillar to a 12v Instantly lost DAB I've had this problem in previous cars I asssume the lead causes interference with digital pick up using the same route. I can't be on my own with this issue??
Bought a snooper and using same USB doesn't work properly and interferes with DAB So I guess accessory is the issue however I don't have another source.
