with my E72 and E73 i do quite often get low GPS signal which means it rarely detects exactly where i am.
With the E72 there is an option called 'Satellite status' which shows me loads of grey bars which turn blue after about 5 seconds.
that seems to boost the signal!
Now with my N900 i dont have that option and quite often find myself waiting for up to 3 hours for it to 'look for GPS'
It downloads the data ok but actually 'looking for GPS' can take aaaages!
I have on there standard OVI maps and sygic mobile maps.
I vagually remember there being a piece of software which boosts the GPS signal or maybe even my 3G signal in order to achieve voice guidance quicker for the GPS software.
It's the same result whether or not i use my SIM card or the phone offline, get the exact same result.
sometimes it will find the signal but quite rarely.
A-GPS will not help if you use with no SIM unless you have a wlan connection.
For some reasons, A-GPS never work for me with WLAN connection. Neither supl.google.com, or supl.nokia.com. With mobile connection, supl.google.com works flawlessly.
