cant load maps on htc sedire only with GPS

hi all

I bought hts desire 2 days ago and very impressed with it.

but started to get annoying with Google maps.

Either I dont understand how it works or my desire not working properly.

With no problem I can connect to GPS and can see its on but when i go to Maps application I cant see anything except flashing blue arrow. Maps dont load

My maps loaded when I connect to WiFi.

Does it mean I always have to connect to GPS and internet to load maps?

Feels strange that i cant see any maps with only GPS on.

Can you please hel me.

Thanks

 

thanks,

will I need internet everytime i use maps or just once to load maps?

 

oh, how annoying

do you know any app that can store maps? thanks
