Fitted MP3 player now instruments acting up

[pennypincher]

I had an MP3 player fitted at the weekend and also had a rear light bulb replaced,but since then the Fuel guage is erratic,the rev counter doesn't work and the rear light has blown again.Could a fuse cause all of these symptoms?

Get an auto spark to look at it. Could be a fuse issue, an overload, interferance, or a dodgy relay.

Disconnect the mp3 player and see if that helps.

If it does go back to installer and kick there Ar$e
