- The factory radio size is single "DIN", so as long as you buy a
single DIN flip-up dvd-tv-radio for your Diablo and not a double DIN
unit it will fit into the dash of the car fine. "DIN" refers to the
height of the unit in the dash. Older cars often
have a single DIN height for the radio. This means the face plate of the
radio is about 2 inches high. Recent cars are often 2 DIN units. That is
the height space for the radio is twice as high as the older 1 DIN
units. height. Depending on your factory
set up (this car had an alpine unit) the radio was easy to remove. At the
passenger side, near the floor there is room to fit your hand behind the radio
and push it out. In some cars there is a screw back there as well which
has to be removed first.
Remove the radio. Almost all of the wires you will need will be found
here as well. Depending on your choice of new navigation system your installation
may vary from what I have here. A flip out display that not only flips but slides forward
is necessary because the Diablo dash is angled slightly can get in the way when the
radio is in the open position.
Alpine supplies a detailed wiring diagram for anybody to install the
system in a car that has a basic knowledge on auto electronics.
I found a grommet large enough to run my wires from the LCD display thru
the "firewall" behind the wiper motor
in the front trunk of the car. This may have been created by a previous installer.
I am not sure. Regardless, this would be a good place to drill
a hole (if needed). Using a long wire tie I snaked all my wires through
here. I found the front trunk a
great place for most of the Alpine equipment as the interior lacks sufficient
room to install anything.
The only wires that were not in the radio harness were the VSS, REVERSE, and the PARKING BRAKE.
I found the vss at the back of the
speedometer. There is a 3 wire plug. The black with red wire was the vss.
The parking brake wire was found at the switch at the brake itself. For the
reverse wire I simply used the rear backup lights wire. I did this for 2
reasons. First I do not have the Diablo wiring schematics for this car and was unsure if
this wire was accessable in the interior; Second I installed a rear
view camera. This make a great addition to the car since without it is
is sometimes very hard to see behind the car. This camera needed power from
the reverse light lead as well which I had already located in the
rear of the car. The camera itself cost $250. The camera,
(figure x), is shaped like a license plate holder. I found
the factory mounting brackets flimsy and not acceptable. I replaced them with 1/2"x1/2" aluminimum square tube mitered at 45deg. at each
end. This allowed access to the back of the holder nuts through which
the wire could could also be run.
There is a grommet behind the drivers seat. Remove the glove box and the grommet is exiting to the
engine area of the car. You must remove the drivers
rear wheel and inner wheel well to access the other side of this gromet.
This is a great time to zip-tie the wiring the sub-frame along the top
of the cavity. Let the wire exit the rear near the lower radiator.
Remove the radiator screen an continue to secure the wire.
Note, there will be a learning curve when programing the vss to the
Alpine GPS system. Drive for a mile or so will correct any factory
installed setting on your system.
