Garmin 1450 Rookie Puzzled

 

I programmed a route from my office to my home.

I noticed tonight two things while I was driving home

1) The speed (on the right bottom) of my Garmin 1450 was sitting at 20 MPH and I was driving 45 MPH and then when I stopped, it was showing 48 MPH.

2) The arrival time (bottom left) of my Garmin 1450 was showing the direction I was traveling as in (North) . I turned the unit off and turned it back on and it was showing arrival time on the bottom left

why is this happening, I have set everything I want Saturday this week? I have made no changes....

Thanks very much,

Rich
