Yes a few possible problems here:
- no maps on the phone. you need to use the nokia pc suite or similar app to down load the maps from the web & transfer to the phone.
- cannot connect to data network. If you're on another operators nw, easiest is probably to call customer support & they can text you the settings for your phones. Can usually also do this from 02.ie, vodafone.ie etc.
- gps not working/not picking up a signal, even when outdoors in open space. I've had this problem occasionally. Best to try a 'hard reset', i.e. turn off phone, remove battery, wait 1 min, power it back on and try again.
