Posted: Mon Mar 12, 2007 7:55 am Post subject: Doe's anyone know how to Manually Relocate GPS Location |
|
|
Hi, I am away on holiday soon, and was wondering if anyone knows how to Manually relocate the GPS on a Nuvi 350. We are leaving UK in 3 days and going to Florida, I know the unit should do it automatically once there but I just want to cover any possible problems. I have in the past read somewhere about this, but for the life of me can't find the post. Any help would be appreciated |

Never had to do it - but I believe it has something to do with reloading the almanac information that is used to 'best guess' satellite positions.
Not something I would recommend and I'm not even sure it would be possible with a nuvi. My GARMIN handheld GPS(es) implement the GARMIN protocol for doing this. I have used them in Europe and USA and they have gotten a lock in under 15 mins each time without doing anything. I know that there is an option on the GPS60 and GPSII+ (and similar units) that when it can't find any sats it prompts you to select a "nearby" location (usually a major city) and I suppose it uses this info to manipulate the almanac info.
I would leave well alone and when you get off the plane turn on your nuvi and leave alone for several minutes - it'll be fine. You'll have a few mins waiting for immigration clearance :D and I bet the 350 will pick up some signals inside the building. _________________ Phil |

You can set your current location to be Florida (or anywhere) if you just want to play around with the unit as if you were somewhere else? Is that what you want to do, or are you trying to do something more complex?
With the GPS arial closed just view the map, press anywere on the map to get it out of navigation mode. Zoom out (a lot, if you need to zoom out to see America), zoom back in to your desired location. Then click anywhere on the map and you should be given the option to 'Set Loc'. Once this is done you can then simulate navigating to a specific address, or POI, or just look around at POI's close by. |

On the older Garmin units there was a satellite screen which showed the location of the the sats. From here you could choose a new location which was useful if you had moved more than a thousand miles from your last location. You could also use it if you wanted to plan a route - you could set a new location (choosing your start point) then route to your destination and it would create the route.
These days, the SiRF III chipset doesn't have such a problem finding it's satellites when you have moved a big distance so you don't really need the "new location" feature. It might take 5 minutes with a good sky view to get it's first fix in the new location but other than that it should be fine....
If you are getting a hire car then plug in and set the Garmin first then put all your bags in the car and fuss about. By the time you are ready to go it should have a fix. :D _________________ Gone fishing! |

Thanks to everyone for your advice, I think what RavingDave mentions will do. I know the previous method which I could not find the posting on was a lot more complicated, but it sure looks like what I was wanting. Once again Many Thanks to all. :D |

Whilst SiRFIII is more sensitive it doesn't really help in getting a position fix (except in low signal areas) when the unit is moved a long distance.
The problem is that the GPS unit can't make sense of the information it is picking up - it doesn't correlate to the information it holds internally about the sattelite geometery. The initial delay is while it is waiting for ephemeris and almanac data to be broadcast by the sats. It's this data that is used internally to give the unit a picture of the satellite geometery essential for calculating a fix. I think the GARMIN "set position manually" screen on most handhelds manipulates whatever data is in the unit to approximate the almanac/ephemeris data for your chosen area. _________________ Phil |
