Thread: Is it possible to turn a mobile phone into a GPS?

This is quite a common practice @Wintrr however I have noticed some discrepancies between bearings to a landmark on my compass and the phone GPS/topo50 combination. This could be down to they way I use it though and I'm interested to hear other member's thoughts.

My experience is that topo50 is not a replacement for a purpose built GPS, but can provide enough direction to get you roughly in the right place.

Always carry a compass though.
