Midland MicroMobile MXT115 Installation

Thankfully Midland stepped up and offered us their new MicroMobile MXT115 GMRS mobile radio. Boasting 15-Watts of power this 'little' unit should serve our travel needs well.
We chose to install the unit in our 1998 Toyota 4Runner, affectionately called June. After much thought, we decided to mount the unit in the dash, directly below our Yaesu 1802 2m radio, where the factory ashtray resides.
Tools and Supplies

Mounting the radio in place of the ashtray does require the dash to be modified a bit. First, we started by removing the radio panel fascia. I won't go into much detail here but you can read how to do this over at 4Runners.org. Although you might be able to modify the fascia with it installed, we found it to be a lot easier when removed.Step 2: Removing the Ashtray

Step 3: Modifying the Radio Panel Fascia
The ashtray opening is slightly narrower than the radio mounting bracket and will need to be modified. To start, place the mounting bracket up against the fascia and mark the extent of the interference with a silver Sharpie. Then, carefully cut the portion of the fascia that interferes with the bracket.
Step 4: Mounting the Radio Bracket
With the excess plastic removed from the fascia, slide the mounting bracket into the ashtray opening and align the mounting slots up with the ashtray slide mounting screw retaining clips. Using a Phillips head screwdriver, insert the ashtray slide retaining screws into the retaining clips.
Step 5: Running the Power
Although the MXT115 is supplied with a car power (cigarette lighter) adapter I chose to power the unit from the auxiliary fuse block I previously installed in the driver-side kick panel. To do this I modified the supplied wiring harness by removing the fuse assembly and soldering on extensions to the positive and negative wires. I routed the wiring over the steering column and attached wire terminals to the ends. Before I buttoned everything up I applied heat shrink to all of the soldered joints to prevent corrosion or possible shorts in the wiring.
Step 6: Installing the Antenna
Step 7: Finalize Installation
With the power wires and antenna cable run now it is as easy as connecting everything up. Slide the wiring harness and antenna cable end through the back of the fascia and attach to the back of the radio. Slide the radio into the mounting bracket and coil up any excess antenna cable and secure with a zip tie. Before you reinstall the radio panel fascia take a moment to make sure everything is working properly. Turn on the radio and attempt to communicate with a second mobile unit or hand-held radio. If everything is functioning properly, reinstall the fascia and mount the microphone mount.
