I know you help alot in Garmin.
I have a Garmin GPS had for 17 yrs now but it's not a Navigator, I also have a TT and it has a problem so I posted for help and Not a single Expert or member replied, so that's how helpful members are here, and as soon as a Forum has a problem the weak run like Rabbits.

If these posts keep going may move it to GPS Free Talk.
