FITTING GUIDE
1. Open the glovebox and you will nd a circular piece of plasc in the rim, pop this out of place and it will
reveal a screw that holds one secon of the fascia in place.
1. Open the passenger side door and proceed to pull away the door trim from the pillar.
STEREO REMOVAL
DAB ANTENNA INSTALLATION
2. Using a set of panel removal tools, begin to pry away the pillar casing.
4. The DAB antenna not only has a self adhesive backing, but also features a black earth sheet. When plac-
ing the DAB antenna, the earth sheet MUST be placed onto the metal part of the pillar. The antenna itself
must be located roughly 15cm from the top of the windscreen.
Note: this antenna must not be placed atop any kind of heang elements, this will interfere with the
antenna’s signal.
5. Once happy with the placement, take the 3m of wiring extension and feed it down through to the
stereo’s opening. With the wiring adjusted to the appropriate length, feel free to re-install the glovebox.
3. The glovebox will need to be dropped down to route the antennas wiring. To do this, rst unclip the
glovebox side panel. Opening the glovebox you will need to remove 3x bolts located on the inside lip, 2x at
the far back, and one underneath. Once free, simply leave in the footwell.
FASCIA PLATE SET-UP
1. Aach the brackets that come with the kit to the relevant sides of the stereo. Place into the vehicle and
roughly test t with the fascia to measure whether the brackets need moving forwards/backwards.
2. Aach the yellow grommets onto the back of the new fascia to mirror the OEM fascia. When done set
to one side.
3. Undo 4x bolts that hold the radio in place and remove whilst disconnecng all of the wiring.
DASH MODIFICATION
Some plascs will need to be cut and removed from the dashboard to make space for the new car stereo.
Measure where the stereo will sit and take due care when modifying the vehicle. TopVehicleTech always promote the
help of professional installers. TopVehicleTech will not be held responsible for any damage to the vehicle.
2. Take a hold of the p of the fascia panel by the fans and rmly disengage from the clips. Repeat this
process all the way to the radio, removing the panel complelety.
