Pros: I use this GPS receiver with my Nokia E63 (Symbian OS) for car navigation and like GPS data logger for my bike trips. Some main experiences:
- work fine with Nokia Maps and Sygic Mcguider
- position is fixed in 60 second
- google maps works fine too (but there is no voice navigation in Europe)
- saved GPS logs are in KMl format (Google Earth can open it)
- BT is automatically ON after start- then you can connect your mobile phone etc. After 5 minut withount BT conection bluetooth is automatically turn off and only data logger is active (power save)
- GPS log work great in my pocket :-)
- small and light machine

Cons: - plastic body seems cheap :-(
- there is only bluetooth conection (no USB)
- there is no case included
- GPS Track Tagger is not very friendly software- there is no direct export function etc.

Other Thoughts: - in Win 7- I have to run "GPS Track Tagger" like admin for proper function
- saved GPS logs are in "GPS Track Tagger" folder in "data"
- for BT reactivation you have to turn device off and then again turn it on

Bottomline: Good machine with nice price. It work like GPS receiver with my phone and like GPS data logger too. But body material and included software are not very good.

Pros: Very fast shipping !
Pretty good built quality, works very well, in so much places,
Works perfect well in my Nokia 5530!
Works whit all Original Nokias accessories.
Battery lasts much.

Cons: Whit nokia maps, it dont show where is "radar"
I think there is no other cons.
if you have a Notebook/ PDA / Cellphone whit bluetooth BUY IT !.

Other Thoughts: You can download "Google maps" in your cellphone/pda to use whit GPS.
This device is great comparing other devices available in same price level.
3 LED indicate the status of Bluetooth, GPS and recharging provides a nice information about GPS.

Bottomline: Works like any other GPS system, i like it so much.

Pros: This device is great comparing other devices available in same price level.

Cons: No battery charge level indicator, but it's not problem if you charge it after every use.
Plastic seems quite fragile.

Other Thoughts: It does what it needs to.

Bottomline: Buy better battery sku.32404
With sku.32404 battery lasts about 20-22 hours without Bluetooth connection.
Works perfectly with sku.11866 bt-dongle.
Code for pairing pc and gps is 0000
BT connection is available about 5minutes after turning device on. It turns off automatically.
Data recording starts automatically when you turn the device on.
Included software is GPS Track Tagger. You need this software to adjust GPS configuration settings (logging time etc). Its also possible to disable data logging and clear all recorded tracks.
Quick guide for included GPS Track Tagger software:
First adjust correct com-port [ Tools->options ] according to Bluetooth configuration
Then [ File->Read Track ]
Route data is stored under program installation folder \Data\
You can import/read this data to Google earth program.

Pros: very cheap
simple use
comes with car cigarette usb charger adapter
uses standart sized nokia charger
uses standart sized nokia batteries

Cons: -the software only supports windows.
-there is no usb connection option, only bluetooth serial connection.
-skytraq chipset

Other Thoughts:

Bottomline: i think it has the biggest performance/price ratio. but its nearly impossible to use it on different operating systems than windows. one can try using gpsbabel with new skytraq chipset option to read the log, but i find the dualboot option to be the best solution.
