Navman just searches for GPS

I searched using https://www.google.com and could not locate a manual for that model.

The link below to Navman in Australia may be helpful to you:

Dear Leszek,
We have no ability to help you except to recommend you enter this information above into the search engine of your computer, and particularly look for the "navman" website.
God bless your efforts.

It means it's searching for GPS birds. The initial process may take up to 15 minutes for the unit to locate enough birds to locate itself. after it's located the birds and itself, subsequent power on sequences should be shorter in locating the birds.

i have just bought second hand navman icn310 need manual turns on and keeps saying waiting for gps ?

Run the Navman software in XP emulation mode. Do a word search in Google for "XP emulation mode in Vista" to get instructions on using emulation mode.

go to factory reset under spanner and keep pressing next till reset comes on

The CD is not available for download from Navman it seems, but you can get it at thepiratebay.com. Just search for 'navman icn' and you'll find what you need, I just did. Better learn how to download torrents though! :)

10-15 minutes is normal.
Did you take it outside? GPS doesn't work indoors. Try in an open field, no trees. Should lock in a few minutes. I always do the following: i key in the destination address at home, then put it under 'favourites". When i start driving, i put the unit in my car and look up the recently added favourite. The unit then has enough time to lock on to the satellites.
