Hello everyeone, recently i've decided to buy a GPS for Nokia 770..
I was wondring, anyone who has GPS for Nokia 770, how would you rate it, is it good or bad, out of 10?
Which GPS adapter should I buy ??? (I have no clue whats so every which one I need to buy.)
Do I need any SOFTWARE to instal on my Nokia 770 for GPS or it comes with adapter as a CD?

Thank you

Hi Hi-Liter!

I have a Wintec WBT-100, which I would rate around 6. It does the job, but it is not very sensitive or particularly fast to fix.

While I don't know for sure, I think that any Bluetooth GPS supporting NMEA output should work fine with the 770.

Regarding software, I highly doubt that the GPS will come with any Nokia 770 software. Your best bet is to install Maemo Mapper, which works quite nicely on the 770. You can also install Roadmap (a 770 version, the latest ones are usually compiled for the 8x0) if you want to use vector maps.

I've just bought a Bluenext BN909GR, it has a Sirf star III chipset which is supposed to be pretty good (go for the 20 channel version of the chipset).

The other competitor atm (afaict anyway) is the MDK chipset with 51 channels (there's an earlier 32 channel chipset, but I've not seen any comparisons of it). This has lower power consumption and is almost as sensitive (1dB difference), but was more expensive when I was just looking.

In terms of software, try maemo-mapper.

A receiver that supports more channels isn't necessarily better. The number of channels refers to how many satellites the receiver can track simultaneously. There are only 32 satellites in orbit (only 31 actively transmitting) and a maximum of 12 can be in view at any point on the earth at one time. Any 12 channel receiver should work just as well as a 20 channel. As far as a 51 channel receiver goes, I'm sure it exists, but only because they know that most people will think it's better because it has more channels.

I know, the only reason I mentioned it is that it's a reasonably easy way to differentiate between the revisions of the chipsets as this "# channels" is always mentioned
