Drove 5 hours last night in the darkness to get to Virginia Beach.
The TomTom is awesome....extremely accurate. Love the navigate to point of interest thing! Found the diners quick with correct drections.
The MPH was 1 higher than the car speedo. I'd say that was pretty darn accurate.
The only thing that seemed to be an issue was the quick battery drain. But I guess that is just a minor thing since it has the power cable.
Established contact with 7 sats. Darn thing even worked in my house....how does it do that? I thought it had to have a clear view of the sky
How does it work in your house? the same way a TV and radio work,with an antenna,but the more obstacles you put between the antenna and its source,the worse the reception gets. GPS products today have very good reception and will work in the house,but the bigger or thicker the obstacle the less accurate they will get or even quite working.
My hand held GPS and the 2 on my boat actually have a screen showing the satellites that you are receiving from and there orientation in the sky above,some will be overhead and others on the horizon,and below will be a bar graph for each one showing the signal strength and you can see how obstacles interfere with the signal of each. a GPS only need 3 satellites to work,4 is good but 6 is best,so even though it works in the house you may not be getting reception from all available satellites but you are still getting enough for it to work.
Thats why i answered your earlier question the way i did,you asked about accuracy and i said Dead nut's on with a clear site to the sky,accuracy will diminish some with obstacles.
You should of owned a GPS when they first came out to the public,accuracy sucked. The military and GOV have what is called a user switch that they can flip,it has been turned off for several years now,but when it is turned on :crap: your GPS is inaccurate up to a 100 feet or more.
