I have an old GPS38 that is refusing to find and lock onto satellites Garmin say this model was discontinued a long time ago and could not suggest how I could fix this problem Does anyone out there know how to reset this model to its factory defaults? Will this fix the problem? I also have a GPS 12 and fear this may also develop the same problem as it is also old and no longer 'supported' by Garmin. Right now the GPS 12 is behaving fine. Whilst not used a regularly as before, I do check both models when clocks change from UTS to summer time twice a year & the problem with the model 38 has only come to light in the last 6 months??!!
