Navman sleeve 3450 not working

Hi all,
I've just bought the Navman 3450 for my Ipaq 3970 and the GPS function is not working.
The installation went well, but when I use it I see always in the bottom "waiting for GPS" and when I go to GPS status, the screen is showing me always 0 satellite (even after 1 hour in the middle of the garden). But in this screen I have on the top the field saying that the system is linked correctly (COM6: Navman IPAQ GPS).

I have updated the version of Smart ST Professional to SP2 (1.91.0045) and I have added the latest serial driver from the Navman US website.

I aso installed Win Fast Navigator (from Leadtech) to see what was coming from the GPS. From there I've seen that data are coming every 2 seconds, but the data concerning the localisation are always empty.

So I don't know what to do anymore Crying or Very sad

Do you have experienced the same problem?
do you have some ideas of what I can try next?
Is there a Navman support in UK?

Thanks in advance for your help. Mr. Green

Usually the 3450 sleeves are much better than the older 3000 and 3400 sleeves which did have major problems receiving a fix. If you are seeing data coming through in WinFast Navigator, then the receiver is receiving data fromt eh satellites, but it may not be receiving enough to obtain a fix. When in WinFast Navigator, if you leave it for 15 mins, on the Navigation screen, do you get any green circles ? Or are they all red or blue ?

It could be that the sleeve is in factory mode and requires a full factory fix, but even then this should only take 12.5 mins on a clean run.

It might be an idea to contact Navman Support, they have a contact page at http://www.navman-mobile.com as it might be a dodgy sleeve.

Hi,

I have a somewhat similar situation: I just bought (secondhand) a 4 month old 3450 and iPAQ 5450 and just cannot get the 3450 to fix at all.

Watching the GPS-status screen I notice some satellites being received (up to 10) but only once in a week did I get a fix. This fix was not very reliable and kept dropping out.

When I received the set I immidiately upgraded the 3450 ROM and also the SmartST to SP2. In this forum I have seen some doubt as to whether the SP2 should be used on Win2003 only. I therefore reloaded the software to the SP1 that came with the unit. But still no luck.

I have also seen some sugestions as to turn off the IRDA (how do I do that ?) - but is this actually necessary ?

The cold facts remain: I really do not know what to do now Crying or Very sad

Hi,
Thanks for your help.
I have upgraded the firmware, and from the quick test I've done it seems the GPS is now working.
I will test it more in detail during te week end, but I already managed to have a fix which is great.
Thumbs Up
