Previous unit was showing "Mechanism error" but would play the CD more then it showed error eventually. So anyway mechanic replaced it with another blaupunkt (secondhand) but turns out it's worst then the first that was in there, it's not playing Cds at all just showing "Mechanism error", no hope in this one. Has anyone replaced there 08 VE SV6 with an aftermarket head unit? Planning on ringing the Mechanic and letting him know it is not working at all. This is driving me nuts.
