Some factors to consider regarding the built-in GPS in the N810:

- The further away the current location is from the last location, the longer it takes the GPS to get a fix
- I get a fix a lot faster with my N810 when the battery is fully charged or when it is connected to the AC adapter
- There's no GSM radio or A-GPS, so there's no way to help the GPS get a fix using the location of nearby GSM towers (like on the N95)
