Question about Navman ICN 635 GPS Receiver

1 Answer

Operating temperature Navman icn

My ICN 630 has worked perfectly for years, but now will only work at above about 60 degrees.
I can switch it on but it goes off without loading maps when below 60deg. Put it in the sun or somewhere warm, and it is fine.
I have updated all the updates and reinstalled all the software.
Any ideas please
Tony

The unit has two temperature sensors that prevent it from overheating - there is one on the circuit board, and one on the back of the screen. Sounds like one has gone faulty!

Try hitting your reset button if you haven't already. I had the same problem and this worked for me.

Navman icn 520 stuck on USB screen


I had this problem when I completely deleted the Backup folder from \My Flash Disk.

Restoring the backup folder allowed the 520 to operate properly again.

It is possible that you have a corrupted APPStartupSec.exe application. Without this file working it appears that the NAVMAN waits in USB mode for ever!

Hope this helps.

There are two possibilities:

1) it is a software problem, in this case you can solve it downloading and installing a firmware update. You can download latest software from here.
This is most likely situation.


2) If the above did not work it means that you have an hardware problem, probably the touchscreen is slightly faulty, or the lcd ribbon cable is not well connected. In this case I suggest to take the navman to service.

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! :)

Misssing SD Card for NavMan iCN 330


I have a 310 and purchased an SD card for France from Navman, it says it works in the 310/320/330 so my guess is that a 320 map will work in a 330.
