Hi Rob,
I've replied to your PM, but I'll post the reply here for info.

Hi Rob,
having read your last PM, I think you are getting some sort of shielding effect from the panel and the iPhone holder.
As you said it's fine when not in it's holder, but loses connection when you place it back in it's holder, I'm pretty sure this is the case.
When SkyDemon says it has lost GPS what it actually means is it has lost the WiFi.
Your proposed solution of moving the wifi dongle with a USB lead should get around this issue.
Didn't we replace the WiFi dongles already, so I'm pretty sure you've not been unlucky enough to get 3 bad dongles !
I think your solution will fix it, as you already know it works when the phone is not in it's holder. Moving the wifi nearer the holder should circumvent the screening.
regards
Dave.
