The maps were around £1.80, the app is £6.19 I got a friend to import pocket queries to maps (scuba_2) he's well up on this kinda thing,I can now put my phone into airplane mode,leave the gps on,find the cache using the map and radar (that comes with the maps once caches downloaded I think.yet again it's down to scuba_2) then go onto Groundspeak,put in my log and save it until I get home,on with my wifi and send logs.
Yet again it's all thanks to scuba_2 you could look him up and ask for assistance,he's very helpful.
