This guide should apply to all Hyundai Elantras from 2007-2009.
From stock to Awesome!
- Metra 99-7326 Single DIN Installation Kit
- Metra 70-1004 Radio Wiring Harness
- New Radio (In my case a Pioneer MVH-X380BT)
- Soldering Iron and Solder
- Electrical Tape
Step 1). Loosen the Surrounding Fascia
Note the location of the gray clips below on the backside of the fascia, prying up around these points easiest. I had the most luck working on the lower left and right corners as a starting point.
Step 2). Remove Wire Harnesses from Fascia
Once the fascia itself is loose the 3 cables that connect to it need to be removed. Start by depressing the clip which connects to the back of the hazard lights. Shown in the photo below.
Next remove the two wiring harnesses that connect to the clock (black wires) and passenger airbag sign (yellow wires) above the radio.
Step 3). Remove the Stock Radio
Unscrew the four screws which surround the unit.
Disconnect the wire harness and the antenna cable from the back of the radio.
Step 4). Prepare the Adapter Cable
At this point I took the Metra Wire Harness adapter cable and started soldering the wires to the new wiring harness provided by the new headunit. Which wires will need to actually be connected will vary based on the capabilities of your headunit.
When looking at the photo below you can see the adapter cable beneath the stock wiring harness that stretches over the black adapter which plugs into the back of the new headunit. I took the liberty of wrapping all my wires in the harness together with a little electrical tape but you don’t HAVE to do that, it’s just a nice touch.
Step 5). Install the New Headunit
Connect the wiring harness adapter from metra into the stock wire harness. Then screw in your mounting bracket from metra using the four screw which previously held the old radio in place.
I choose to mount my new head unit using the ISO mount technique which is a bit simpler than the classic DIN method (which employs the metallic cage surrounding the headunit which needs to have some pins bent down to hold it in place). Using the ISO technique requires the removal of the DIN cage from the new headunit and attaching the side rails included in the metra mounting bracket kit. At this point, connect the cables to the back of the new headunit and slide it into place.
I choose to run an additional microphone cable that was included with my headunit for handsfree calling but don’t have any pictures of that step.
At this point you can replace the fascia and then add the trim bracket which surrounds the headunit.
