Three times over past two months my radio has demanded code for no apparent reason suggesting power interuption. Now it has packed up completely, I thought bad power connection but seem O.K. Checked fuse but OK and others on same fuse alright. Is it likely to be connection inside radio? K reg so not worth getting brand new radio.
It certainly sounds like a bad connection somewhere, check if you have 12V at the radio connection, if you have not got a test meter you can use a bulb. If you have 12V then it could be a connection inside the radio, It probably isn't a fuse as the radio would not have worked until you replaced it.
