When we travel we have at least 4 phones in the truck so using mine for the Echo was a no brainier. Having to grab a manual trailer brake knob or button is usually to straighten out your rig while towing. A semi (TT Unit) passes you and your rig starts to dance a little. A tap of the trailer only brakes straightens you out most Riki Tik. I have not used the new application yet but plan to with my dual axle Horton Hauler (HH) enclosed 16'x10' scooter mover very soon.
I remember back when we trailer camped as kids and when my Dad had to go for the trailer brake; it wasn't in the best position to use, in my opinion, but it could reach under the dashboard with the wires that came with it when mounted close to the bottom there...and all it did was remind us it was there when you hit your legs on it on entry/exit...
I installed your Media Mount just for my i8...and this function. It's in the perfect position for the manual brake button for my 100 series. I think I may add another 1" ball for underneath your MM for another X-mount too. The feature I look most forward to playing with on the Echo is the different brake sensitivity settings. They can be placed into 1 of 5 memory presets. My HH Lite / Medium / Heavy loads all require specific setting that I had to adjust prior to each different trip. Nothing tips off the on-looker of a rookie quicker than skidding trailer tires because the light trailer is set for a heavy load right?
I Love Your Media Mount...

I added some hammered metal finish to it and the RAM stuff to soften the look...

I could probably go a little darker in the shade but it is an awesome use of waisted space the cassette tape player took up...
