Generally speaking, your sat nav should be perfectly ok on your dash, it does not have to 'see the sky' through all your car windows, although as mentioned tall buildings will affect it, as could a heated front screen. i bought one about 2 years ago here in the uk and was concerned because my car had a heater element in the front screen and i was advised to get an external ariel, but i didnt actually need to. so if you have a heated front screen, this could be the problem

Hello pdeland,

In order for your GPS to calculate its own location, it needs to receive data reports from four or more GPS satellites. This process is normally pretty fast and will typically take approximately two minutes. However, this assumes that the GPS has a clear view of the sky.

Obstructions such as tall buildings, trees and local terrain such as mountains and hills can affect your receiver's ability to "see" the sky. This is also true of GPS's used indoors or inside of a vehicle. A GPS receiver without a clear view of the sky can take a long time to get a fix on its own location.

The process can also take additional time if the GPS has been powered off for an extended period of time or if you have travelled a long distance (greater then 500 miles) since it was last turned on.

Hope this helps!

    Hello again pdeland,



    The GPS probably has a better view of the sky from the seat. From that location it can "see" the sky all around the car through the windows, enabling it to quickly receive signals for the required number of orbiting GPS satellites.



    On the dashboard the GPS likely has a good view of the sky out the front windshield but may be blocked above above and behind by the metal body of the vehicle.



    You might try investing in an external antenna. Having an antenna outside of the vehicle would likely solve the problem for you.



    Best Regards,

    Ken

Hi, Just opened a new 1490LMT. Can't get a satelite signal. Small red bar appears on left top corner. Also, I'm in Winnipeg and can't get the GPS to acknowledge Winnipeg. Toronto is on screen.


Hello,

When travelling with your GPS it may take 20-30 minutes for it to acquire a satellite signal. For it to acquire the signal it should be stationary so when visiting the family or in the hotel leave it on you should get satellite lock.

Hope this helps!

Magellan roadmap 760


The Magellan 760 has been around for a few years now, and unfortunately, isn't one of the fastest units around when it comes to synchronizing to a satellite. I find with mine that the time it takes to lock onto a signal depends on several factors:
1) Having the GPS mounted in a way that allows the antenna to have a clear view upward 2) Having my vehicle in the open, so that the signal isn't impaired by adjacent buildings, overhanging trees, etc. 3) Being stationary while the GPS attempts to get a lock. It has more problems locking while moving. 4) Ensuring that the GPS is used frequently, as it loses its memory of what satellites it's synchronized with if you happen to be in a different place when you turn it on than the place you were at when you last turned it off.
Those last two points have the most affect on my GPS's performance. I find that by turning on the GPS and just parking in my driveway or parking lot for a few minutes will allow the GPS to acquire a signal in a much shorter time than if I start to drive immediately. While this will waste a bit of time on the front end, it does help you get synchronized more quickly

Acquiring signal


My wife replaced the car kit.
The sportster itself was fine, what fixed the problem was replacing the cradle.
Now the second one has taken a dump.

Garmin NUVI 650 acquiring satellites


  • Make Sure the GPS has a good, clear view of the sky. “Clear” does not need to be sunny. Overcast skies have no noticeable impact on GPS performance. But buildings and trees do. So take the GPS outside where you have the biggest sky view as you can.
  • Next, wait for the GPS to acquire a signal. If this is the first time you have used it, expect it to take up to 20 minutes to find a signal. Most often it will take less, but prepare for 20 minute. Now for an important step… Once it has found your location, let it continue to sit there for about 30 minutes.
