I have been using my fathers Garmin 276c with the included auto bean bag . The unit itself is very nice as those of you that use it or have a garmin. I have a 2002 4Runner and space is limited for mounting accessories. I like the clean stock look when it comes to the addition of anything. For instance my on board air is under the hood and utilizes factory threaded holes, and a defrost switch for activation. My cobra cb is mounted in the armrest and serial plug is out of sight when the mic. isn’t plugged in. I get a lot of the ideas from multiple sites such as this one and Slee Offroad. Knowing the unit wasn’t going to be mounted on the dash I picked a better location just forward of the 4wd shift selector .
I started by test fitting the round mount was going to sit on the concave surface, I shimmed it using 2 Toyota shock mount washers with two sided tape. After verifying it would sit level and not wobble I secured it in place with small self tapping stainless hardware.
I then picked a good spot for the ext. antenna. I though about mounting it on the hood, using a sticker under it to prevent chaffing the paint. Then an even better spot presented itself just in front of the drivers side windshield wiper. I used a piece of 3M super 2 sided tape and used my clevis hitch plug to weigh it while it was bonding.
I then routed it through the firewall and re siliconed it to prevent interior driver side floor flooding as is common with 4Runner’s if the firewall plug hasn’t been siliconed after installation of aux. Item requiring power from under the hood.
After checking my connection I used the supplied speaker/ power unit so turn by turn is audible. I had a hardwired connector but no audio device, this also keep the device slightly more portable. I love it and it looks good and works very well.
