2720 Getting confused?

[njbhorn]

Just some advice for the best way to get my 2720 up and running when leaving work to go home.

I work in the City of London and emerge from a car park where I switch my unit on. I find if I let it come on inside the car park it decides it's indoors etc. so I give it a fighting chance by switching it on outside.

However when it has booted up I then select my route home and set it to navigate the route. I then ride off and it seems to take an age to acquire satellites and sometimes it is 2 miles or so before it sorts itself out. Yesterday I was at Euston Road and had to reset the route before it sorted itself out. It was showing a map with a large scale at one point which was no use at all.

I appreciate that central London does not have a clear view of the sky but once it has sorted itself out it seems quite happy.

My question is does the unit take longer to sort itself out whilst moving rather than when it is stationary? I have tried waiting whilst stationary but it seems to take a long time too. Valuable moving time when you want to get home!

Any suggestions for the best approach would be appreciated. I understand it takes a finite time to sort itself out but would like to know the best sequence of switching the unit on, setting the route and acquiring the satellites.

Many thanks for any help.

Regards

Nigel

I'm no expert but...
whilst I understand it does take longer to acquire whilst moving, your real problem is that in london there is a poor view of the sky due to all the tall buildings.
Try stopping at an 'open' cross roads where the GSP should be able to 'see' plenty of satelites.

...your real problem is that in London there is a poor view of the sky due to all the tall buildings...

Yeah, I think that about sums it up.

Most GPSRs seem to be better at 'holding onto' the satellite constellation when their view of the sky is poor than they are at 'acquiring' the satellite constellation when their view of the sky is poor.

I don't think it is any more difficult for the GPSR to acquire the satellite constellation when it is moving than it is for it to acquire the satellite constellation when it is stopped, provided that it has a steady, uninterrupted view of the satellites it is trying to acquire. When individual satellites are constantly disappearing because the sky view is being blocked, it's kind of tough for the thing to get its mitts on the constellation and grab hold of it for the first time.

Many thanks, I guess it's as expected really.

I shall just have to stop at the Aldgate Station roundabout/racetrack and wait for a fix

Trouble is standing still in London seems to be discouraged!

Just got my GTM 12 so keen to see how that works in the big city too.

Have you switched the Auto Zoom to off?

 

[njbhorn]

Ta for the advice, but no, I'm happy for the auto zoom to do its stuff but in central London you don't normally get many opportunities for a large scale map, unless you get on the North Circular or some such beast. Normally in this area it's fairly small scale, but for some reason the 2720, bless it, got all of a tiz and didn't know where it was. I had to reset the route etc. which was very difficult as the traffic lights kept changing and I haven't mastered the art of using the controls whilst negotiating nutters in cars and on bikes.

Also the screen says not to do it whilst moving when it boots up

Just wondered where you got your GTM 12 from and at what price?

 

[njbhorn]

globalpositioningsystems.com

About 150 quid.

Have seen it cheaper but they're a good reliable site.

Seems a lot of dosh for a tiny bit of kit but it seems to work well, comes with the lifetime subscription and completes the gps package.

Only had quick test on way home and it showed problems on M25 but didn't go that far to confirm accuracy.

Hope this helps.

How come you don't know your way home from work?

Good point!

As I'm new to biking I like to experiment with differnet routes and I'm not very good at turning pages of A-Zs whilst riding so I plan my routes and try them on the way home.

I must admit I now have my route pretty much spot on but one thing the GPS does it gives me an estimated time of arrival and that is great. Also it reminds me of where the speed cameras are, always a bonus.
