Let us know how you like it after some testing. I have an older 3G( it may be older than that) model hard wired into my truck and it past time for a upgrade. It has worked well, the only thing i had to modify was a reset switch. Mine is wired behind the seat in the crew cab and had no reset button. At times when I spent too much time in a dead zone, it would time out and quit looking for signal/boosting. Its wired through the fuse panel so only live when my ignition is on. I installed a spring loaded toggle on the dash and switched the terminals on the back so it was on, and when flipping " on" it would momentary kill the power to reset the unit.
Did you wire up to a switch, or constant hot?
