i HAVE THE 700 UNIT.

I often have to press the touchscreen buttons multible times to get it to function. Is this common? I did the screen calibration.

I have latest update, but still have to wait awhile for unit to work from start up.

There must better GPS out there, but I am keeping this.

You gotta let it do its thing when booting up for a like atleast a min or so. You impatient or what..
