Head Unit Install

Any DIN or Double DIN radio will fit in the dash with very little trouble. You will need a few parts and info about these parts first.

1.   Wiring Harness
I highly recommend using a METRA wiring harness (part #70-1398). With this harness you will not have to cut and ruin the clean Toyota wiring. The harness should cost around $10 USD, a small fee for a much cleaner, and easier install.  

2.   Mounting Kit
You do not need a kit to install an aftermarket radio into the MK2. Instead you need the factory Toyota metal brackets off the OEM radio.   

3.  Additional Parts
If you are installing a single DIN radio, you will need to order a Toyota factory pocket (part #55521-16010) that fits directly below where you are going to mount the aftermarket headunit to fill in the area that will be void.

The Install:

Removing the OEM Radio
Remove the heater control buttons, they pull straight off their respective arms.                         Remove the 3 Phillips head screws on the face of the heater control panel.
Remove the heater control panel, pull straight off, should be very loose now that the screws are missing. This will reveal two more screws at both top corners of the rubbery black radio surround (RBRS).
Remove the two screws.
Remove the ashtray. This will reveal the four screws in the RBRS.
Remove the four screws.
Remove the RBRS. You will need to unclip the harness for the cigarette lighter and A/C switch. Once the RBRS is out of the way, you will see four silver or gold screws, two on each side of the OEM radio hold those much needed metal factory brackets.
Remove the four screws.
Remove the radio. You will need to unplug the harness, and the antenna plug on the back of the OEM radio.

Preparing the Aftermarket Radio for ISO DIN use
First thing we need to do with the aftermarket radio, is open up the install manual, and see what you need to remove to make it an ISO DIN install. I know you will need to remove the radios outside trim panel that surrounds the radio, as well as any parts that hold the metal cage around the radio. You will not be using the aftermarket radios metal cage.
   
Use of the Factory Toyota Metal Brackets
Now that we have the OEM radio out, you need to remove the screws holding the factory Toyota metal brackets on the OEM radio, save the screws.

Place these in the respective order back onto the aftermarket radio.  If you have trouble lining them up with the screw holes on the aftermarket radio, the brackets are labeled R for right and L for left for reference.  

If you are installing the single DIN radio you will need to install the pocket below the radio at this time. You most likely need to trim the two little tabs at the top corners of the pocket. If they are not removed it leaves a little gap in between the radio and the pocket. They are only there to fit into the Toyota factory radios, they are NOT visible once installed, there or not.

You will most likely be using the screws that held the metal factory brackets on the OEM radio. If they do not tread into the aftermarket radio, the correct screws should have came with the aftermarket radio, look in the box.
   
You should have everything physically together. If you have any problems please feel free to Email Me.

The Wiring
95% of the popular aftermarket Radio wiring will EXACTLY match up with the colors of METRA wiring harness. You might have a few wires left on either of the units, that are not connected to each other.

If you get confused, The METRA wiring harness, and the aftermarket radio will have a description of what each wire goes to, Just match up the descriptions.

If you are missing manuals, and get stuck, just Email Me with the exact model of radio, and I will search my database and send you the information.

Done       

That should be it, Installation of the radio is reverse of removal.  Just a reminder so you do not have to take the radio out again:)
