    • The aluminium backplate is held in place by four large screws, so remove these first. Then gently pry off the backplate, since in is glued to the plastic back cover. The bottom of the aluminium plate curves around the bottom; this part can be used as a hinge to open.

    • Behind the aluminium plate, the plastic back cover is held into place with ± 10 screws; removing these allows it to be removed carefully.

    • The interior of the radio, with the power supply on the left, held in place by four philips screws, and some glue here and there. At this point the data cable to the controls was still connected.

    • The four-wire cable (black-black-red-red) provides both 5V (black-black) and 10-12V to the radio. Other people have found out that the 5V is only needed for the USB power outlet in the back, so that the radio can operate with 12V only, only losing the USB power functionality.

    • For this repair, the power supply has been replaced with one from a broken television that happened to be available, and gives 11.5 V, which proved to be enough. Since this power supply is a bit bigger than the original, it has been mounted to the back of the interior, with sufficient space between power supply and other components.

    • Two wires have been soldered to the power supply, and the red wires of the original cabe have been cut, to connect these to the power supply. Soldering these wires has been done, whilst making sure that 0 and +12V have been connected to the correct wire.
