Hi,

You'll probably get a reply from Stephen (the author of TMJ) soon, but in the meantime, I'll let you know my experiences with what you said.
First of all, the internal GPS receivers in any phone tend to be fairly insensitive. You will almost get better results if you buy an external Bluetooth GPS receiver. They cost from about 20-30 quid, and in my opinion are a worthy investment, even if your phone has an internal receiver.

Secondly, you say 'sitting in a chair'. Are you indoors? As no GPS system will work very well unless you are outside.

As I understand it the compass and bearing dials will not work if you are standing (or sitting) still, as the GPS/TMJ has no way of knowing which direction you are facing unless you are actually moving. I would guess the elevation should work, even if you are stationary, but see me previous points about getting an accurate GPS fix.

Hope this helps,

Regards,

Chris.

Hi there,

Although there is a chance that some providers may block the use of the GPS by third-party apps like TMJ, it doesn't sound like this is the case here as the GPS is clearly giving *some* data - does the Text/POSITION screen (press [1] a few times to access it) give a reasonable latitude and longitude for your location? If so then it should work okay when moving.

As Chris says, many of the gauges are based on 'derived' data which is only reliable when moving and with a good GPS signal (so don't test it stationary indoors!). I'd definitely suggest going for a walk or cycle and see if it improves - it should do!

By the way, the internal GPS (usually) updates it location once a second, and as TMJ also redraws the screen once a second, this should explain why the gauges are appearing to fluctuate at the same time.

Any luck?

Cheers,
Stephen

Bit confused myself too!! Could you try the following please:

- Reboot the phone (BB8900 shortcut to do this is LeftAlt + RightShift + Del).

- Install the version from this website again.

- Stand outside somewhere with a clear view of the sky.

- Start TMJ and use the Menu/GPS/Connect Int.GPS function to activate the internal GPS.

- Monitor the Latitude/Longitude fields on the Text/POSITION page and also the GPS Status field on the Text/GENERAL page. Give it up to 5 minutes to get a fix (the initial phone reboot might increase the delay but ensures that it starts 'from scratch').

If the Lat/Long field does get a fix then walk up the street and monitor the gauges. The GPS Status field should also show an incrementing number (after the # symbol) confirming that the phone hardware is supplying TMJ with GPS info, and if so then the plan page [4] should should a track of your walk.

Also, see these notes for more detailed troubleshooting steps.

Any luck?
