I hope so :-) TI themselves say "High performance: The GPS5300 NaviLink 4.0 solution enables a rapid time to first fix (TTFF) from weak satellite signals, exceeding the GPS requirements for 3GPP and 3GPP2 operation."

Anyone has the 3GPP specs and knows if there is a TTFF requirement mentioned inside?

I only found this tidbit from 2000, related to A-GPS as supported by the chipset: "[Without the assistance information] the Time-to-First-Fix (TTFF) could be in the range of 20-45 seconds."

That would be acceptable Currently, it is too slow for me.

Well Nokia does not sells the N810 stating it's a "GPS device". It sells it as a companion for your laptop that ALSO does GPS.
They don't sell it as TomTom or Garmin or Magellan do.
So there is no point in complaining about that.

If I would have looked for a good GPS than I would have looked for specific GPS products.
I do use GPS maybe twice a year and sometimes just for fun.. why would I need an expensive GPS chip ?

By the way, my 29€ bluetooth GPS receiver took almost half of an hour to get its very first fix (while my N810 took less than 5 mins!).
True, my 29€ bt GPS receiver takes few seconds to get a fix if I turn it off and on (within few hours from turning it off), while the N810 still takes its 5 mins EVERY time I try to get a fix.
But, for me, it far more than acceptable.

Note: "for me"

Is this a fact? I thought E90 had SiRF II?

I've actually gone and bought the Wayfinder software (one born every minute I hear you say).

But seriously, apart from the initial 2-3 min (for me) delay as I set up in the car, I find that it performs well. I'm hopeing the initial startup time is improved, but it does seam to do a good job once it has got a lock.

Done over a 1000 miles with it now and on the whole I'm quite happy. Love having the Traffic updates included. Works a treat. Though they really do need to update the Speed Camera Database. It seams to spot the ones that are there, but there seam to be loads of false alerts as well. From previously removed devices I assume.

For me it also does a decent job. However, startup time could be improved using maybe some other information like current broadcast cell the phone is in or so.

This pointer clearly states that the GPS is a ti 5300.

I've been seriously considering the eePC, but without Bluetooth capabilities, I'm not able to get online as easy as I do with my N800 since there aren't that many WiFi access points on the go, e.g. while having my lunch at a fast food restaurant, waiting for my wife at the airport, checking for specifications at various car dealerships or at the garage, etc

Plus, from personal experience, with WiFi running, I've only managed to get 2 hours of battery life off an eePC while online browsing and getting my emails done. I'm able to pull off a good 4 hours or so off my N800.

That said, when it comes to document creation and composing lengthy email replies, I'd be more inclined to get the eePC.

The eePC will become a feasible alternative for me once they get the following sorted out:

- Bluetooth DUN
- Expansion battery packs (hot swappable, for a maximum of 6 to 8 hours on a single charge, or at least 4 to 6 hours online)

I've only managed to tinker about with the eePC for a day. it's a good idea, but it won't replace my N800 until the two points above are sorted out.

Not to confuse CHEAP with "Best bang for the Buck"...

TI introduced the industry's first single-chip assisted global positioning system (A-GPS) solution in 90 nanometer (nm) process technology for mobile phones. A-GPS enables consumers to connect to a satellite from their mobile phone to get directions and maps to the nearest ATM or store, find friends who may be nearby and location information in emergency situations. Through TI'sinnovative DRPTM technology, the GPS5300 NaviLink™4.0 single chip offers the smallest system area for a discrete GPS solution, lowest total system cost, low power consumption and high performance A-GPS functionality.

"A-GPS capabilities are becoming a must-have feature for 3G mobile phones in many regions around the world,"said Marc Cetto, general manager of TI'sMobile Connectivity Business. "A low bill of materials, small size, low power and high performance are fundamental requirements to drive A-GPS penetration in mobile phones, all of which TI delivers with the GPS5300 NaviLink4.0 solution."

The snag is that A-GPS needs cell data from a mobile phone. Has anybody figured out whether the needed information is accessible through a public standard interface? If not, that would restrict it to Nokia telephones.

well, according to the wikipedia article,

All you need is some kind of connection to an assistance server. It doesn't necessarily have to be on a cell phone network.
