CD changer no longer recognised by HU
My first post on here some months back was about my GT's rear shocks imbalance and failure of the NCT/MOT after new shocks being fitted.
That has now been cured with another set of new shocks.
However after getting the car back from the garage the CD changer in the boot is no longer recognised by the stereo.
I presume this is due to the mechanic failing to reconnect the wiring correctly in the boot, which also has the bose amp and sub woofer.
Is this a job I can remedy myself? Will I have to remove much of the boot lining/plastics to get at the wiring? Is the CD changer lined into the amp or the HU?
I have already had to return the car to the garage to have some damage at the jacking points touched up and don't want to have to return it again.
Thanks in advance.
