The other cause might be a CAN bus conflict, especially if they're
running something like the OBD2ECU task. The CAN busses are plumbed
out both of the OBMSv3 connectors, so bus conflicts are easy to
create.<br>

if the module affects your car's builtin navigation system, I
think that points to some EM interference. While the module has
passed the EM tests for certification, it still emits some EM
noise, and some devices are more sensitive to this than others.
There also may be a satellite outage affecting Australia
currently, that adds to the sensitivity.<br>
<br>
You could try to selectively switch off Wifi and the modem when
the issue occurs, to see if one of these cause it.<br>
<br>
If not, you could try reorienting and replacing the module in the
car, especially if it's very close to the nav system's GPS
antenna.<br>

<div dir="ltr">Hi all,<br>
<div>I'm having a bunch of weird things going on which
seem correlated to having the OVMS running. I'm not
convinced of causation yet.</div>
<div><br>
</div>
<div>My car's Nav system is drifting out majorly (like by
>100m) and then seems to stay out. This causes major
distractions as the nav system keeps giving me warnings
about going down one-way roads and it makes the
navigation 'interesting' to use.</div>
<div><br>
</div>
<div>I also noticed that Android Auto location was frozen
in one place, so I assumed this was coming from the car
- or meant to be anyway. I reduced the polling rate
(new work I'm doing) slightly and this freezing no
longer happens. (To 3 speed queries per second). But
the drifting out on the Navigation still happens... but
then not on AA!? Very very weird.</div>
<div><br>
</div>
<div>If I unplug the OVMS from the OBD port (as I'm
driving) it seems to (but not immediately - after a
minute or so) correct itself. It's hard to confirm this
is directly resulting .. but it seems to be?</div>
<div><br>
</div>
<div>I turned off my ECU2OBD which should mean that it is
resorting to 1 per second POLL with a low throttle
value. I'll run with some logs to make sure this is
what is happening.. but it still seems that this hasn't
stopped this issue from happening.</div>
<div><br>
</div>
<div>I've tried turning the GSM power off. No result.</div>
<div><br>
</div>
<div>Another note: I seem to have stopped getting anything
near regular updates from the OVMS GPS. Every now and
again it gets a successful change come through. Still
working on diagnosing that.. maybe it's related?</div>
<div><br>
</div>
<div><br>
</div>
<div>Any thoughts / help would be useful.</div>
