I have now tried two different internal antennas (one from my GTA01Bv4) on that device and still no signal at all (not even the time). Attaching an external GPS antenna worked. The GPS reportet the time within ~20secs and after additional ~40secs I had a fix. I repeated that several times and while the external antenna always got a fix the internal antennas I tried didn't get anything. My guess at this point is that either the antenna selection or the phantom voltage for the internal voltage is broken, but I haven't looked at the schematics yet so that assumption may be silly.
