Race Radio Communications with Bluetooth using P.C.I.’s TRAX Ultimate 4 System.

Communication is an important part of any adventure. It sounds simple enough, but it isn’t always. A simple handheld radio may suffice the safety needs, allowing you to reach out for help in an emergency and even give basic communications between vehicles in your group. It is often, however, a glorified walkie-talkie. Racers have been using intercom systems for years, they allow open communication between driver and passenger as well as a direct link to support crews without having to even stop driving. Push to talk at break neck speeds. PCI Race Radios recently launched a new system that gives non-racers a far better way to have that same communication, the TRAX Ultimate 4 system.

Designed for UTVs, sand cars, and prerunners, the TRAX Ultimate 4 system with Bluetooth is loaded with hardware that not only gives superior radio communications, it also has music and cell phone use options with Bluetooth connectivity and a hardwired audio connection jack. Now you can properly listen to your favorite adrenaline pumping music while blasting down the trail.

TRAX systems from PCI are available in several formats. The individual pieces are available, as well as packaged sets with two to five headsets or helmet wiring kits. The TRAX Ultimate 4 system includes four headsets, the TRAX Stereo Bluetooth Intercom, Icom 50-watt VHF radio, antenna, push-to-talk buttons, and the all the necessary cables. PCI spent the required time to set up a good system that’s easy and straightforward to install.

The TRAX Ultimate 4 Bluetooth Intercom System is a prepared package that includes everything but the XP1000 specific bracket. PCI includes a handy bag to stow the headsets in when not in use so they don’t get damaged.

We spent some time at Dependable Off-Road in Anaheim, California, as they installed a PCI Race Radios TRAX Ultimate 4 system into a ’16 Polaris RZR XP1000 using PCI’s XP1000 specific radio and intercom dash mounting bracket. Follow the captions for the basics of the install and refer to the PCI instructions for more info.

What’s Included

TRAX Stereo Bluetooth Intercom: Two Trax five-pin 12-foot, and two 16-inch headset/helmet cables with quick-disconnect nexus mil-spec connections; optional upgrade to digital signal processing (noise cancellation)

TRAX Stereo Headsets: Four full stereo, high-quality, carbon-fiber, over-the-head¬–style headsets with built-in coil cord; featuring new full range, HFI speakers, gel ear seals, and cloth ear covers

Icom F5021 Mobile Radio: 50-watt, VHF, alphanumeric display, 128 channels pre-programmed with stock desert list; option to add notes to your order to include special frequencies

Antenna and Coax: 17-foot hole mount coax and no ground plane antenna

Push to Talk Buttons: One Velcro and one panel mount

Music/Phone Audio Input Cable: 6-foot cable, allowing you to input music into your intercom or voice conversation from a phone or music device

Always disconnect the battery on the vehicle before doing anything with the wiring and electronics to avoid potential damage from shorting a circuit.
The Polaris XP1000 comes from the factory with a handy secondary glovebox in the middle of the dash. The PCI bracket is designed to replace the box and put your comms right in the middle for easy use. The box clips into the dash at the front with a support bracket that needs to be unbolted through the top.
After pulling the mini hood off the RZR, you can access the bolts that secure the dash to the body. The dash will then have enough movement to unplug the switches and information display as well as give enough room to access the bolt that secures the glovebox support bracket.
With the dash out of the way, you can now see how the PCI XP1000 bracket bolts in.
The new bracket slides in from the top. Two bolts secure the top to the dash and two bolts secure it to the bottom, where the glovebox used to reside.
With the bracket placed, mark the holes that need to be drilled for the lower bolts. Remove the bracket then drill.
Reinstall the bracket and insert all the hardware.
Install the TRAX Intercom first. Once the radio is installed, the space to reach the backside of the hardware is very limited.
For a clean install, the installer at Dependable Off-Road decided to route all the wiring under the center console. The console comes out easily with the removal of a few bolts and push locks.
After getting the intercom and radio installed, route the wires down and plan out where your wires will go.
To keep the wires out of the way and less likely to get snagged by a foot while running down the trail, a hole was drilled in the plastic in front of the center console.
All the wires were routed and zip tied along the center of the vehicle.
The console was then reinstalled. The headset wires were pulled up through each of the seatbelt holes so they are close to the seat they’re designed to be used with. This will keep dangling wires to a minimum.
The Ultimate 4 System includes an antenna and coax cable. The XP1000 getting the new system had previously had an aftermarket cage and roof installed so a hole was drilled through the sheetmetal to securely mount the antenna. The coax cable was zip-tired along the cage and down the passenger A-pillar and then behind the dash to the radio.
To keep the headsets accessible when out on an adventure but when they aren’t on your head, a pair of PCI’s Headset Hangers were installed.
That’s it. Superior communications and Bluetooth connectivity is just that easy.
