FITTING GUIDE
1. Using a set of radio release keys, push them into the 4x ports found at each corner of the main radio.
STEREO REMOVAL
FASCIA PLATE SET-UP
1. With the main radio removed from the dashboard, place the new inner mounng trim onto the open
aperture and screw it into place with some self tapping screws (screws not supplied).
7. With the stereo situated correctly, simply place the new fascia over the front of the stereo.
2. Once done, simply pull the radio out of the dashboard and disconnect all the wiring.
6. Once the “Stereo Installaon” process is complete, simply push the stereo into the cage opening unl
the unit clicks into place.
2. Aach the brackets to the new stereo. These brackets allow you to set the specic depth of the unit in
relaon to the fascia plate. Start by lining up the spacers (Fig 1.) on the inside of the plates
(Fig 2.).
Fig 1. Fig 2. Fig 3.
3. Aach the spacer and plate combinaon to the corresponding side of the stereo using the screws that
come with the stereo. Test this set up outside of the dashboard by sliding into the radio cage.
4. Take the fascia in hand, and place it atop the caged radio combinaon. If the depth/alignment of the
stereo hangs out too much/is reccessed to far, use the radio removal keys (Fig 3.) to release the stereo
from the cage and repeat the process.
5. When you’re happy with the bracket alignment, proceed to install the cage (without the stereo) into the
dashboard. Then bend the tabs to ensure the cage doesn’t move.
