i just purchased a refurbished garmin 478 from an ebay store a couple weeks ago. just wondering if it taking 5 to 7 minutes to aquire satellites each time i turn the gps on is normal??? i think i read somewhere in the manual that it may take longer to aquire satellites if you haven't turned the gps on in a while. but when i ride to work in at 630am and then turn the gps on at 5pm, it doesn't save the time (would say its like 11am or 12pm) and takes over 5 minutes to aquire. that to me is not a long time...weeks or maybe months i would understand but not being able to in the same day??? i know when my father in law turns his zumo 550 on, it immediately gets a signal/aquires satellites. is this right?
