Headset and Ports/GPS - - wierd drop outs

[jimbo_hippo]

OK here's a strange one. Orange SPV M2000 with Navman Smart ST V3 amd a Holux GPS cradle (which uses the com port on bottom of the phone so its hard wired).

Since installing I have been through a process of elimination to find out why the software reports NO GPS DATA occasionally, especially when it had to do anything that involves loading something, i.e. a speedcam warning or voice command approaching a roundabout. Tried the lot. Disabling ports/activesync etc.

Then one day it dawned on me that it wasn't happening on a long drive North from London. The only thing that was different was I didn't have the headset plugged in!

I've tested this over the last few weeks or so, and yes, headset plugged in means loss of data from the GPS intermittently.

I installed TOM TOM 5 from a friend and low and behold it seems to be doing the same. In TOM TOM you get the signal bars at the right and they go to zero every couple of minutes then spring back up. So its not software specific.

I would have thought the supplied headset was just a good old-fashioned 'feed to the speaker or feed to the earpiece' hard connection but it would appear not to be so.

So the question is, what is the Blue Angel doing when the headset is plugged in that it isn't doing when its not?!!!

OK, ....I know, ...I know, ....if no one has posted it probably means no one knows the answer :cry: So I'll ask, does anyone use their Blue Angel with Navman SmartST V3 who could try this with the headphones to see if its a one off or a real issue?

As a test I installed TomTom Navigator and it does the same thing.

Any thoughts appreciated.

OK guys. I know I can't force a response so I'll post findings to date. For one reason or another, I have used Navman Smart ST V3 (now returned) a 'borrowed' version of Tom Tom navigator 5 and, in an effort to remain 'legit' a version of Destinator PN. All these exhibit the same problem so I can only presume that there is a hardware issue with the Blue Angel and my GPS port (port 1). Does anyone have a clue what the BA does when you plug in the headset that could cause such a problem or pehaps even a fix?

I have an XDA IIs with TomTom 5 and a wired GPS unit.
It doesn't exhibit this fault.
The headset (wired) works just fine. I have disabled BlueTooth to get reliable telephone performance, so I can't tell what that would work like.
