not sure if anyone else has had this problem before but my spedo doesnt work and use to come on and off occasionally. after fitting my new head unit i noticed it then but was told the head unit wouldnt effect it but maybe thought that during the fitting proces as the cables go behind the dash a cable may have come lose. i also get random warning lights come on but there is nothing wrong such as oil level and engine warning light.
if anyone can help please do.
cheers
