Hi,
I have a 2014 A3 SE 2.0 TDI with the Audi Satnav. Every so often, the satnav loses my position and, as you can imagine, colourful language and some chaos follows. I now carry a "backup" TomTom.
The satnav will stay "lost" for a while, and only normally finds itself again after the vehicle has been parked overnight, or a after a few days. I have done some extensive searching on various forums, and the concensus seems to be the the antenna needs replacing. This makes sense, but 2 things suggest otherwise.
1). If the GPS antenna has failed, why does it appear to magically start working again after a "rest".
2). The satnav only seems to lose it's position when I'm actually using it to guide me. If I'm driving around familiar places with the map displayed but no route guidance, it doesn't appear to get lost or lose the satellites.
I'm still testing point 2 at the moment, but if this is the case, this, to me, looks more like a software/firmware issue rather than hardware (i.e. a failing antenna).
Clearly, I'm going to have to take it to my local Audi dealer to get them to check it out. Either that, or sack the Audi Nav and use the TomTom, which also came with FREE updates.
I'd be interested if anyone has seen similar. I find point 2) above particularly intruiging.
Regards
Ian
