HELP!! Navman 4400 Bluetooth Conection Problems.

wildpig

Hi all,

I have recently purchased the 'Navman 4400 Bluetooth Wireless GPS' unit and have experienced many problems with the BT connection becoming disconnected and therefore 'No GPS DATA' can be obtained.

The equipment I am using is:

IPAQ 3870
Navman 4400 BT GPS
The IPAQ has BT manager 1.1 installed
PPC 2002
SmartST V2.0
Maps are loaded onto 256 SD media
Plently of memory is left on IPAQ
IPAQ has latest drivers etc.. (including latest serial driver)

I have also performed soft reset only to have the Navman pick up the sat's again and then after about 1 min they drop back out.
I have also performed a hard reset and setup everything again and this still does not fix the problem.

I am ready to hand the Navman 4400 back to the shops and get my money back as it's just far to unrealiable.

Any suggestions?

What's the speed settings for the 4400 receiver? Are you running it at NMEA 38400?

Hi Ibendlin,

I have been running it on 57600.

Also, noticed on the UK support site to turn off 'receive all incoming beams and select discoverable mode' under start, settings, beam settings.

This may cause dropouts on the bluetooth connection. Something to do with it can get confused with sunlight etc..

57600 is the speed for the jacket versions BlueTooth receiver normally work best at 38400. Have you tried that?

Success Today!!!

I did what you said, switch it to 38400 and also turned off 'receive all incoming beams' and it never dropped out once.

So thanks heaps for the tip. (hopefully it will last & work well)

Also, I have also noticed that sometimes the map data gets inverted?

example: you maybe traveling up the road to somewhere etc... (so the screen is scrolling upwards)
You reach that destination and then power off and then later when you power everything back up again, rather than pointing north, the map has kind of inverted and you are traveling down the bottom of the screen all the time. (the street data is correct) but, rather than the map scrolling up. It scrolls down all the time.

I hope you get what I mean? Have you seen this problem before?

I was wondering if it's a software fault?

Cheers!
