The internal GPS in my Nokia N95 8GB can take some time to get an accutate 'Fix' (The GPS antenna is housed within the numeric keypad, so the screen must be slid up during use. It took a while to pinpoint my location – often over five minutes). An apporoximate Fix, using Assisted-GPS from Cell Sites, is much quicker, but is rather innacurate, perhaps by as as much as 1Km or so, as you experienced.

Once the GPS has locked on to enough Satellites with adequate Signal Strength, it is accurate to about 3M (depending on Number of Satellites and Strength of Signal)

I often use an external Bluetooth GPS logger (Wintek WBT-201 G Rays2), rather than having my Nokia N95 8GB, exposed to the elements (hot sun, and vibration and rain on the Motorbike, potentially as well)

I have Garmin Mobile XT application on my Nokia N95 8GB and have become a 'Contributor' of RoadGuide.ph and have V1.21 map installed.

This WBT201 is also much quicker to Sychronise, than the Internal GPS on my Nokia also. The Bluetooth GPS Logger, is good for up to 10M from receiver, so the phone can be anywhere in the car, or safe in a pocket or in a belt holster, when used on my motorbike.

Google Earth now offers direct support for WBT-201 (along with Garmin and Magellan), as does GPSBabel.

Semsons offer good Support - I got Free Holder and recently (3 years later), the Battery cover fell off and I lost it. They contacted 'Wintec' in Taiwan, and are getting me a replacement (Free) from Wintec.

Many Bluetooth GPS units to select from, at much lower price if you don't require Data Logging, but I like the WBT-201 as its 'native' GPS format is supported (GPS-Babel / Google Earth), so not limited to using the supplied Software (TimeMachineX) to extract the GPS Logs.
