sat nav

bladebrew

my first time starting a thread
just a quick question,can you use a sat nav outside a car? ie. if your out walking will it still work just the same or does it need to be plugged into a power source all the time?
someone told the girlfriend that a satnav will only work when inside a car,and that it knows when its in a car!!!!

sorry if this is in the wrong place
cheers!

Course you can use it outside a car. Mine used to last about an hour on batteries

Once it has batteries and a self contained antenna, you can use it outside the car.

just make sure you dont leave it out in the rain, you can get some waterproof models that can be used on Motorbikes, IE Garman ZUMO 550, I find them handy walking around London if im there on a night out.

all that option will do is slow down it's calculations. Most representations of motion on your system is calculated based on the assumption you are moving at a certain speed which is why, when you turn off the route, it takes a few seconds for it to realise it. It reduces data traffic loads on the satellite.

So your walking option will slow things down to a 4/5 km/h pace.

See?

It also affects how it calculates routes - pedestrians are not subject to one-way streets etc.

How can it 'reduce data loads on the satelite' when there is no data sent back, its purely one way and uses multiple satelites to work out where it is. All the walking option does is ignore one way systems as it doesnt apply to pedestrians and obviously a pedestrian can't walk along a motorway.

Yes, it does work outside your car and i've used it for find addresses in cities perfectly fine.

How come a Garmin handheld comes with the facility for the company to trace it for you if it's lost then?
