Antenna on windshield/windscreen
To route the antenna cable up to the front windshield/windscreen, you will need to remove the
fuse-box cover (one screw that needs to be turned 90 degrees), then two screws from the box
below the fuse box (these screws should be completely removed in order to be able to remove
the box and access the compartment beneath). You do not need to adjust anything in the fuse
box - you only need the cover removed to make it easier to route the cable.
Start with the cable at the windscreen/windshield and route it down the side of the left side door
front pillar. The plastic corner can be pulled back slightly, and you can push the cable through
into the open bottom compartment. Pull the cable through there so that the antenna is where
you want it and there is no loose cable outside the box. The antenna itself can be mounted to
the windscreen/windshield by first cleaning the area with a clean dry cloth, removing the
adhesive backing tape, then firmly pushing the antenna against the glass and waiting a few
seconds for the adhesive to stick.
Now for the tricky bit. You need to get the cable through to the passenger footwell, but it is tight.
It is much easier to get a guide wire up into the fuse box compartment than to get the antenna
cable down into the passenger footwell. So, we recommend you use a small (12 inches / 30 cm
or so) piece of stiff wire to use as a guide and push it up from the area marked by the green
arrow on the bottom right of the picture below. Once the guide wire is in the fuse box, push it
down into the lower compartment you opened and wrap it around the antenna cable. You can
then pull the guide wire back down into the passenger footwell, bringing the antenna cable with
it.
The antenna cable can then be screwed in to the OVMS module. You can then tidy up any
loose cable, and screw-back the lower compartment box (two screws) and fuse box cover (one
screw 90 degrees to lock).
