JVC 7" & 10" Head Unit Bundle Installation Guide I '07 - '18 Jeep JK/ JKU Wrangler
Welcome to your Jeep JVC Head Unit Bundle Installation Guide.
The following information will walk you through the entire installation which includes a video at the bottom to follow along.
If you have any questions at all, or need anything during the installation, we're only a phone call away and we're available Monday-Friday, 9am-5pm est. for any support needed, or you can shoot us an email at support@trailseven.com.
Before you begin, please confirm that you have all of the necessary parts and pieces needed to complete the install.
*** Please note, that in some Jeeps, the plastic trim piece in the dash may need to be shaved down in order to slide the head unit into place. It's not all years and the range varies so much from year to model that it's not possible to identify which Jeeps will require it. We've found that with a straight blade, you're able to shave about 1/16" to 1/8" of the plastic piece for the head unit to slide in without issues. The 2017 Jeep in the video did not require it, and the percentage is very low, however it has been reported. ***
1. The Body – Consists of the head unit, black dash kit and our custom wiring harness.
- Make all your vehicle connections as noted in the document below.
- All the plugs are keyed plugs, which means they only fit their match on the Jeep side. All you’re doing is matching plugs – it may look like a lot of wires but it’s simple.
You Will Be Connecting:
USB Retention Adapter
Navigation Antenna
JVC Microphone
AM/FM Radio Adapter
OBD2 Plug
Sirius XM Tuner (If Selected)
- DO NOT POWER ON YOUR HEAD-UNIT BEFORE ALL CONNECTIONS ARE MADE. This will cause an error when the Maestro RR module is trying to initialize to your vehicle.
Additional JVC Installation Tips:
- Sirius XM Tuner - If you selected “Maintain Sirius/XM” at checkout, you’ll receive the SAT1.
- Maestro SAT1: This will already be attached to your new Sirius/XM tuner. The tuner is located underneath the rear chassis of the Sony radio.
- Utilize the factory satellite antenna cable that was plugged in to the back of your factory radio to plug into the provided adapter.
- You will not use the antenna from the SXV300 (which is located in your spare parts bag) since the SAT1 will maintain your factory satellite antenna.
- Inside the dash you may find several square plugs of varying colors (i.e. white, gray or black).
- White/Red – AM/FM Antenna
- Yellow– Factory Sirius XM Antenna
- If your Jeep did not come with a factory Satellite Radio option, you will need to use the provided Sirius XM antenna cable (located in the spare parts bag).
-
JVC Microphone - You will need to use the provided JVC microphone with our bundle. You will need to run the wire and plug into wire labeled “MIC”. We recommend placing it on top of the steering column so it is out of the way and picks up less wind noise, however this can also be routed to another location of your choice such as into the A-Pilar factory mic location as the cable is plenty long enough to reach.
-
Navigation Antenna - Included in your installation parts bag is a Navigation Antenna. Use the provided antenna to plug into the back of the radio. You may choose to mount the antenna anywhere that it can receive signal. We recommend routing the antenna between the dash and the windshield and mounting on the dash. As noted in the video, if you notice an issue with the maps identifying the Jeeps precise location, you may need to relocate the antenna to above the soundbar.
- OBD2 Plug - When you receive your bundle the OBD2 plug will be attached to the appropriate connector for reference. The OBD2 plug will need to be connected to the OBD2 port located under the steering wheel. The wire can be routed behind the dash to the back of the radio. The OBD2 is needed to be able to show vehicle diagnostics and real time data in the gauges and vehicle information screens of your new Sony Bundle.
- The small black plug with the red and yellow braided wire pair needs to be connected to the main wiring harness.

Troubleshooting
First, check the following:
(1) Ensure that all connections are mode between Maestro RR Module and your vehicle connectors.
(2) The Maestro RR may need to be re-flashed with your specific vehicle parameters. To re-flash the module, the module will need to be removed from the vehicle and connected to a computer. Visit idatalink Maestro’s website and click on the green button at the top right of the screen labeled “Flash My Module.”
Enjoy your new radio!
