acquiring satellites - not able to get gpx fix!?

[tecman]

Hi

does your nav V unit occasionally have problems with acquiring gps signal? I have it quite regularly and the only fix for it is to enable gps simulator and switch it off few seconds later. That was the case on 2.70 and earlier versions. switching it off and on also helps but when nav is in cradle you can't do it as power button is not accessible.

I was disappointed to find on a recent trip in Spain that my Nav V lost satellite reception on a number of occasions when others with a 660 and a Tomtom had no problems. Reception loss was usually but not always related to something understandable like being in the mountains or going through tunnels but even when I had a clear sky view subsequently, the Nav V didn't regain reception.

On several occasions it "lost itself" which is to say that whilst no loss of reception was reported, my position was shown in some totally arbitrary place on the map, often just a blank white space, or amongst a whole set of roads that bore no relation to where I was. I could see that the tracklog, which I had set to record, showed a track that conformed to the road I was on which suggests that the satellite receiver was working but that the unit had no idea how to show this on the correct map.

I wasn't aware of the GPS simulator trick and had to stop the bike to turn the unit off to regain reception. Naturally, it isn't necessarily convenient to do this!

looks like we are having same issue. mine is loosing occasionally signal under clear sky too.

I wonder if they will they tell you if they found anything wrong with it and what it was? Or, if they do find something wrong, simply say it's been fixed?

I'll find out in couple od days, but so far their RMA check still says that they are waiting for it despite unit was delivered on Thursday!

My Nav V is behaving incredibly badly in the Alps.

For a device that is meant to have enhanced processing speeds and better satellite location, it is struggling really hard. A friend with a 590 is finding exactly the same. The only way I could force it to find its correct location was to stop the route, turn off the device, whereupon it would find itself again.

I get the impression that the higher detailed maps, coupled to the much higher screen resolution, with sometimes less than perfect satellite signal, is taxing its ability.

I disabled 3D terrain when in Pyrenees and Alps this year, simply because the purple colour for your route was hardly visible when overlayed on dark shapes of mountains. Problem with getting fix I don't think is associated with map rendering performance. What version are you on?

new unit on my desk....worked fine out of the box...I'm patching it now to 2015.10 and latest firmware 2.80....we shall see if it gets "bricked" again....

 

[tecman]

looks like it is working with 2015.10 maps and 2.80 firmware!

In case you ever had to deal with new Garmin device and you see EULA question and setting locale question every boot...it means that you need to get GPS fix and device needs to register some movement...I was close to calling Garming to declade DoA...luckily google saved me from embarrassment and hassle of waiting another 10 or more days for my Nav V!

My Garmin Quest1 is performing flawlessly

PS you lot with twatted twat navs......you can get a plug in external aerial for about a tenner on Ebay.......there are a couple of different types of plug ends though, so make sure you have your kit in front of you when you look.

With an inch square of 3m heavy duty velcro stuff, you can mount the aerial in the optimum place- I used to run mine stuck on the middle of the beak towards the front, with the wire running forwards under the ADV beak protector....looked neat, worked superbly.......I had another one stuck on a short pole on the roofrack of my landrover, 'cos the almost vertical screen of a landy is not good for satellite acquisition.

The Nav V has no provision for an external antenna.

and the problem is not with internal antenna, but software/hardware glitch which occasionally stops GPS from fixing on position.

I updated my Nav V to the latest 2.90 software, which brings with it the improved positional and satelite aquisition fixes.

Last weekend I rode the device around the hilly, cloudy, forested Morvan region, duplicating the routes where I lost satellite signals and / or suffered from the device freezing up last time.

I am happy to report all was well. It did lose its satellite fix just once, on a complicated left-right-left junction on a very small road in a deep valley. Re-acquisition again was quite quick. More than acceptable.
