Tomis and All, Yes, due to small size of Holux M1200 and older chipset, it is not as accurate. I-Blue 737A+ would give you much, much better results. The positioning of receiver makes a difference as well. For example, it will get better reception in a shirt pocket or on shoulder than in a bag or pocket. For iPhone 3GS users, iPhone 4 has much better GPS receiver chip, which allows for faster time to acquire satellites, more accurate positioning and will perform faster and be better with background navigation.

As a user of mobile geo and previously user of wayfinder access I found that many times the location I should arive at is spoken some 20 or 30 meters earlier than it should be spoken. So, is this due to the Receiver? I have Holux 1200 and I am interested would purchasing of Iblue receiver improve the acuracy?
