ABOUT THIS PRODUCT
The KWFIA1 installaon kit allows for the retenon of the vehicle’s steering wheel controls and helps maintain
the original aesthec of the interior when installing a new car stereo. The KWFIA1 gives you everything you
need for a complete install in one box. The components of this kit are compable for the Fiat 500 (2007-2015)
with VDO factory stereos. The wiring harness and interface will retain the steering wheel controls, factory phone
buons and features a factory amp turn on wire (if vehicle is equipped). This kit also contains a lead that will
retain the USB input through the Blue&Me system. The interface supplied features a Mini ISO connector.
NB: the harness in this installaon kit will not work with vehicles that have a Uconnect system as standard.

FITTING GUIDE
1. Remove the four inner blank buons with a at head screwdriver to uncover radio removal holes. Using
a set of removal keys, pull the radio out and disconnect all the wiring.
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.
5. 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.
6. 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, remove the control
climate fascia panelling to expose 2x screws holding the main dashboard panel. Once these are undo pull
the fascia o.
2. Undo two screws either side of the opening, two screws located within the cage, and the bolt toward
the back of the opening. Then proceed to pull the cage forward rst to remove, and follow on to remove
the vents.
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.
4. Undo the 3x screws on the front, 2x inside, 1x screw at the back, and 2x underneath. Once all of these
are undone, simply pull the glovebox out, and leave in the footwell.
FASCIA PLATE SET-UP
1. 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.).

STEREO INSTALLATION
4. Aach the USB retenon lead between the vehicles pre-exisng connecons and the new stereo.
5. Aach the addional wiring on the harness to the back of the stereo:
Pink - Speed Pulse Green - Park Brake Purple - Reverse Blue - Amp Remote Turn On
6. When all the above wires (and any addional accessories) have been connected, nally make the
connecons between the stereo and the vehicles pre-exisng connector.
2. 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.
3. 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.
6. Aach the extended fan shas to the back of the fascia panel and test that they match up to the “U”
styled brackets aside the new cage.
5. Place the foam pads below the cage in the dashboard. Then proceed to place the new cage to test the
t, when ready to t completely, ulise the vehicles pre-exisng screws.
FASCIA PLATE SET-UP CONT’D.
4. With the stereo brackets aligned, move onto the prep of the dashboard. Once you have modied the
vents, aach the “U” brackets (facing each other) to the open vent shas, this will re-direct the air ow
away from the back of the new stereo (refer to the images below for conguraon of new fans).
With the fans modied, the new “U” shaped inserts
must be placed like so on either side of the new cage,
this will re-direct the airow to the new fans.
RightLe
This is what your new radio set up will look like with
the new air vents/bracketry assembled correctly.
