Other Comments:

The unit came with 2 metal discs with adhesive. It holds onto them very well. Under the battery lid you can see what looks like 2 tiny rare earth magnets.

It has a port for a high gain antenna which it seriously doesn't need (this thing even worked inside my house away from a window!). But if you have a lot of trees like we do in Oregon, it might be a help. Personally I am thinking of getting one so I can place the actual unit in my glove box and only expose the antenna to the direct heat and light of the sun.

Resync time is under a second, I swear. I went into a medium tunnel and it didn't give up until about 1/4 of the way in and resynced the same distance before I left the tunnel.

My unscientific test was that I got 4 days of use before it needed a recharge. I would say I used it 2-3 hours a day. It does come with a car charger. It supports an auto mode where it turns on/off when your car is on/off, if you are using the car adapter

At aroud $90 - 100, this is totally worth it. Side to side comparision it fairs way better than my friend's tomtom or the little garmin that looks like a tomtom.

I bought through an eBay auction for 50$, together with its software (unusable both with my 770 and my TH55 ).
The receiver is fine, tough, good sensibility and good battery life. Immediately paired with the 770 and worked fine apart from the /dev/rfcomm trick which I performed after having experienced the link problems

Good!

TYPE: BT GPS
Works ?: Perfect
Startup Time (avg): 40-60 seconds
Personal Rating: 10/10
Other Comments: Very nice. Associates perfectly (just click scan), auto powers off when not in use. Auto powers on when I tell the meamo mapper to connect. It usually gets locks to 6 or 7 sats of 7 or 8 inside my house not particularly near any window, and the window has a big curtain. In the car it works well inside the armrest of my subaru (where I have a power adapter). Comes with a wallwart -> usb and car adapter -> usb. Basically perfect, never had to reset BT.

Not bad for $70 ish and 65-70 grams or so.

At the moment I have 8 of 9 sats and an average signal strength of, er, I guess it doesn't say. Now I'm at 9 of 10.

Usually 10 or 11 of 11 of12 when outside. The tracks I've recorded so far
look pretty clean.

Claims to last for 20-25 hours of use or somewhere around 10 times
that for standby, I've not verified either claim.

Similart to i-Blue 737 with redesigned shell, higher capacity Li-Ion battery (1100 vs. 1000 mAh). Manufacturer claims up to 32 hours navigation per charge, 400 hours standby. Tracking sensitivity -158 dBm, 32 channels, Bluetooth V1.2.

After initial pairing, Auto On/Off works like i-Blue for smart power control. Built-in non-slip back. Rock solid tracking (avg. 9 or 10 satellites) from car center console bin or coat pocket, no need for dashboard or other visible mounting. Fine companion for N800 with Maemo Mapper.
