QTurns is a PITA!

[lethalsvt]

I do alot of traveling in/around Boston, and there are alot of tunnels that I go through. I realize that I will lose GPS reception..that is a given. But what I CANNOT UNDERSTAND is why in the hell does the QTurn application have to go blank when you lose a GPS signal??!!
I basically have to make sure I have the route written down on a piece of paper before I travel into Boston, because I know once I lose the GPS signal I am basically LOST! This is a PITA, and makes me wonder why I stopped using paper maps at times.
Don't get me wrong, when I have a signal, everything is "peachy". But driving in and out of big cities, it can sometimes be USELESS.
Does anyone know if their is a fix for this problem, or even additional software/hack that will STOP my Ique from doing this? I mean,I am sure I am not the only one with this problem!!

[apersson850]

Yes, you are. The rest of us stay out of Boston! :D

Seriously, I don't know of any fix for this. Complain to Garmin. Maybe they can get it better with the next firmware release, which probably will be released before Christmas.

[Sho-Bud]

I allways drive with the Quemap.
It gives me a better feeling of what is coming up.

[lethalsvt]

But QueMap will blank out as soon as you lose a GPS signal. After that signal loss, everything is gone

[stephanpls]

Everything gone? After signal loss the iQue navigates 30 secs by dead reckoning (using last known speed and movement direction), and after that the position arrow stands still. But the maps stays visible.

Lighten up pal, it was meant as a joke, humour???? dont they have that in Boston????? or did it get lost in those tunnels...lol

[Sho-Bud]

In Quemap, the route will still be visable, only thing what happens is that the map will turn North up.

[apersson850]

I think both are right about this screen bahavior. If the iQue looses the position, then the map image will stay on the screen, and the arrow will halt after 30 seconds (obviously).
But if the 30 secs of dead reckoning leads the iQue into believing that you've left the road you were on, something which is likely to happen if the tunnel in question turns, then a recalculation may start. During that process, the map image (for some obscure reason) goes blank. I still insist on that it would be smarter to let the dead reckoning assume that you follow the calculated route, until proven otherwise. Perhaps we can convince the programmers at Garmin to think the same.

And yes, I tried to make a joke about Boston, but it seems some of it fell on the ground...

Not for the first time!:mad:

Never seen that. I'll go to Boston to check it out then........;)

[apersson850]

Right now, I'm in Aesch, near Basel in Switzerland. There are lots of tunnels around Basel, and hardly anyone is straight ahead.

So what I described happens all the time here, if I use the iQue while driving around. Now I'm of course indoors most of the day, "quietly getting on with the job", so it's usually no problem. But you don't have to go all the way to Boston to test this.

Besides, if you drive on any road (not in a tunnel) that turns, and cover the antenna when you enter the turn, the iQue is likely to assume that you are going straight ahead after a while. That ought to give you the same impression, without going anywhere from home at all. But the problem is greater in a tunnel, since it's then more likely, that the iQue will assume that you are instead on a road that's on ground level. A road just turning around a field may not have any reasonable alternative.

Now I'm gonna attend a class in "understandable jokes"...

Way way too many problems with that. For the iQue to assume you're following the original route would have it presume traffic never gets backed up, you never miss a turn, don't ever stop along the way, detours don't exist and always drive at "average speed"

And the very things it could use the "prove" you were off route are the very things you'd need to to insure you stay on route in teh first place.

You'd only need to be off route by a few thousand feet to make your real position vs. your presumed position to end up being "off the map"

Much better if the iQue gave you step by step instructions and you hit a button telling it you have followed that instruction.

Such as:

1. Turn right at Main Street (and display a map of that area)
2. Drive 2.3 miles and turn left on 3rd avenue (and show a map of that area).
3. ...etc

When you turn right at Main st....you tap the screen. and get instruction 2. When you turn lef on 3rd avenue, you tap the screen and get instruction 3...and so forth.

No presumptions and you get a map of the area that's most important (where you're going to deviate from your current route). Also what most people do if they use a paper map in the first place.

Oh yea, and if you really wanted to try out the presumption method....create a route and have the iQue simulate it while you actually drive it and see how far off you get.

Will they also teach you to understand understandable jokes? :D

[apersson850]

Not if I fail already in the first grade...

What I meant by "assuming you follow the route" was only for the 30 seconds, during which it now assumes that you go straight ahead out in the blue (or perhaps more often the green). Not for ever. That takes inertial navigation, like the 2650/2660 has.

[lethalsvt]

I think this got way too complicated..lol. All I am asking is this:

When I lose a GPS signal, I do NOT lose the map. I lose navigation with the map..obviously, because there is no signal, there is no location.

The problem is that I lose my "second" resort....QueTurns. I lose all the information displayed on that "page". This is a PITA because this is information that does not need the nav system...assuming I follow the turns correctly. (If I go off route, then obviously it would not be that much help unless I retracked to my original postion where the signal was lost)

The QueTurns to me function as a sort of "Mapquest"...so when I lose the voice guided navigation, I will still have some idea of where I am going...by looking at the turns where I last had a GPS signal.

Just make sure you stay away from the Boston Academy.:)

[maxb]

I was confidently planning a trip to new york mostly roaming around in Manhattan ... until now when I read the post :(

Tunnels set aside, how well does ique hold up in the middle of all high-rise buildings? This is a MAJOR concern for me right now :confused:

[Ken in Regina]

Wierd behaviour...

I'm sitting in my basement office right now, so no possibility of a signal. In fact I have the GPS off (antenna down). Actually haven't had the GPS on in a couple of days. I still had my last route on the Map screen. I flipped to the QueTurns page and all the turns are still listed there.

Then I flipped my antenna up. Within a few seconds the turns disappeared from the QueTurns page and the message that "There is no active route" appeared. I flipped away from the QueTurns page to the map page, then flipped back to .... ooops, where the QueTurns page SHOULD be and there it was .. GONE!!.

Close the antenna and the QueTurns page is available again with all the turns from the current route on it.

I don't know how you feel about turning off the GPS at the point where you are getting into trouble, but that is one possible solution...?

.....hmmmmm... You don't want to do this too often. I just tried flipping the antenna open again with the QueTurns page displayed to verify the behaviour I just reported and now the iQue is frozen solid on the QueTurns page. Can't persuade it to do anything else. Now where did I store that message about the various kinds of resets .....mmmmm... Oh yeah .. in the iQue memo pad. DOH! :rolleyes:

I tried and got the same result. I think this is a bug. Why should Turns should become invisible when you loose satellite?

Is anyone listening from Garmin? Does any senior member of this forum know whether Garmin follows up on the suggestions/bug report in this forum? Or do we have to write to them?

Then she picks up without missing a beat on the other side of the Tip O'Neill Tunnel ;)

[lethalsvt]

Ya, but if you are in a mile long tunnel with 10 plus exist in it, you really cant wait for the signal to reconnect

I'll betcha she does, reinbeau. When you lose signal while you have an active route flip to the QueTurns page and I'll bet it isn't there any more and won't return until you get signal again.

...ken... Well, how would you expect it to behave with no signal? I really don't have any problem with the way it operates, and I look ahead before entering the tunnel to see if there's anything I need to watch out for. I also have an external antenna and while I may momentarily lose signal in Boston, it isn't for several seconds, it for moments, at best.

[Ken in Regina]

Ann, I would expect it to behave exactly the way it does if you have an active route and the antenna is closed. The QueTurns page is still available with all of its information readily at hand.

Why the QueTurns page disappears at the simple loss of signal is a puzzle to me. There is no reason for it to disappear, and the fact that it's there when the GPS is turned off (antenna down) proves that there is no technical reason to make it disappear just because there is no GPS information.

Totally bizarre behaviour in my opinion.

...ken...

[si4xp]

Instead of losing the turn-by-turn display when GPS signal is lost, the system should do the following:
(1) In addition to informing the loss of signal, which it does now, the voice prompt should add, "Please switch to QueTurns for navigation until GPS signal is restored", and
(2) It should retain the QueTurn info as it is

WHEN GPS SIGNAL IS RESTORED:
(1) The voice prompt should announce of this fact, and should switch automatically or manually - based on Preference settings - to QueMap view
(2) Re-calculate route, as it already does, if you have veered off-route
