Not Responding error in Garmin nRoute
mullerh
I have a preference for using nRoute, from a navigators perspective when going on long road trips. For some time I have been experiencing a problem with nRoute. I get a "Not Responding" error when I first start nRoute. This happens when I try and zoom in or out. This problem occurs on both my laptop netbook. It occurs no matter what mapset I am using in the mapset select box.
I recently started thinking about whether it was related to the install of a particular mapset or what mapsets were still installed since the problem first occurred.

I uninstalled Metroguide Canada v5 and the problem went away. I re-installed MGCanV5 and the problem re-occurred.

Has anyone else experience anything similar?

Thanks you for help you may be able to offer.

I see from Noeman.org that you are not experiencing the problem on your desktop computer. Maybe your netbook is choking on the map size. What other maps do you have that work and how big are they?

You know you can disable any map that nRoute can see without uninstalling it by removing its key from the registry. For MGCv5, that would be HKLM\SOFTWARE\Garmin\MapSource\Families\MetroGuide Canada v5. Just right click on the key and export it to somewhere you can find it again ( a .reg file) and delete the key. To put it back, right click on the reg file and choose 'Merge'.

Thanks for your response and comment. Yes, the problem appears on both, a netbook and a laptop. Dont't know whether it is related, but they are both dual core processors. The desktop is a single core. When the error occurs, there are two instances of nRoute in the computer's Task Manager. I currently have CN North America, Europe Middle East, Canada TOPO and US TOPO and a few others loaded. These are much larger mapsets than MGCanada. One of the responders on Noeman.org apparently has 39 mapsets loaded in nRoute. Amazing.

The registry entries in all three machines are identical. It's funny that it only happens when I load MG Canada. Perhaps it is related to how I install my maps. I currently have them all in "D:\Garmin Maps" folder, and not in the "C:\Garmin" folder.

Thanks again for your registry suggestion.

Are there ever two instances of nRoute on the desktop computer?

Why are there two instances of nRoute running on the netbook and laptop? E.g. this won't happen by accident. Something/someone is launching both instances.

How much memory on the netbook and laptop? Specifically, is there sufficient memory to support two instances of nRoute?

Do things work better if you take one of the other large map products out of the registry or only when you remove Metroguide Canada?

For whatever it's worth, I have MGCv5 and a variety of other map products (Bluecharts Americas, a couple versions of City Navigator North America. half a dozen trail maps, Ibycus Canadian Topo and Topo Canada) on my laptop and my netbook.

Both computers have only 1GB of RAM. The laptop has a dual core processor. The netbook is single core. Neither of them ever has more than one instance of nRoute running. nRoute works fine.

There should be no issue with how many map products you have installed on the computer as long as you have sufficient disk space. Neither Mapsource nor nRoute ever load more than one product at a time. The maps are not installed into the programs. They are physically installed in a folder(s) on the hard drive and entries are placed in the registry so Mapsource and nRoute can find the map files when they need them.

When they start up they simply review which map products are available in the registry, find the location on the hard drive and load a bit of product info (name, copyright) in order to populate the list of available map products. They only load one product at a time when you select/change the product through either the dropdown list or the View menu.

I don't know about the D:\Garmin thing as the only computer I have that won't run nRoute at all. However, it is easy enough to test using that same key. Move the MG Canada folder to C:\Garmin and change the references from D: to C: in the entries of that key and its single subfolder named '1'. Then test nRoute again.

Ken:
There are not two instance of nRoute running on the desktop of the netbook/laptop.
The two instances simple appear in the Task Manager when the "Not Responding" error occurs. The errors occurs when I start nRoute and when I zoom in and out.
On first start of nRoute there is only one instance in the Task Manager.
Both laptop and netbook have 2G of memory.
I haven't tried removing another larger mapset yet. The problem currently corrects itself when I remove MGCanV5 and returns when I re-install. It even occurs when I have CN North America selected in NRoute (and MGCanV5 installed). Strange?
I suspected quantity of mapsets not to be a problems since they appear to be handled like you outlined. Thanks for the feedback about your sucessful operation on you laptop (dual core) and netbook.

Actually I just checked my Win 7 desktop and all the maps are in D:\Garmin.

I used to have nRoute not responding problems with my xp desktop endlessly until I gave up and removed it. I just installed it again and it works perfectly. Unfortunately, that computer is such a dog's breakfast that I couldn't say what was causing it though.

You might try downloading a program that Ken recently linked that checks all your Garmin maps for errors and see if there is something it doesn't like. It is pretty good at spotting and sometimes fixing problems with maps.

I had a problem last month with Mapsource not being able to find some maps which were not stored on C:. After I moved them to C:\Garmin, Mapsource was able to find them again.

The non-NT maps can be anywhere you want them. They must be installed there though; you can't move them yourself unless you modify the registry. JaVaWa GMTK can do that for you though.

Terry,

Have you used GMTK to copy registry maps from one computer to another? It wasn't obvious to me how to do it so I used Backup/Restore.

In GMTK I selected a registry map version of one of my CNNA maps and did a backup to a network drive then I installed GMTK on my netbook and tried to get it to restore that backup from the network drive to the netbook.

No joy. When I point it at the folder on the network drive that contains the backed up maps it tells me there's no backup there.

No big thing because I just copied the relevant folder to the netbook, exported the relevant registry entries from the desktop PC and merged it on the netbook and it's working fine. I was a little disappointed the GMTK didn't work as I expected it to.

Have you found a way to get it to do this?

That is not truly moving a map to another drive. However, I just tried it between my XP and Win 7 desktops using an old Ibycus one as it wasn't on the Win7 one. I chose Custom and pointed to a Garmin folder on the networked Win7 D: drive. I then installed GMTK on that computer and asked it to restore. Again I chose Custom and pointed to the D:\Garmin folder. It found the file and offered to restore it.

I'll have to admit, I haven't figured out backup/ restore using the root of a drive yet though.

Now I understand it. If I don't use Custom. It must be a local disk. GMTK prepares a folder called 'GMTKbackup' on that drive letter. Now, to restore, I would have to move that drive to the computer I want the map on...OR use Custom. However, when using Custom, I must identify the folder. Therefore, I would navigate to the networked drive the file was on and choose the GMTKbackup folder.

If I were using a USB key, I would just address the different drive letters it presents itself as on each computer and would not require the Custom designation.

There has to be more to it. I chose Custom Folder and pointed it at a folder named "Backup" on a shared network drive on another computer.

It created another folder with a big long name and inside it it simply copied the map folder from C:\GARMIN into the folder it made.

So we have \Backup\Long Folder Name Created By GMTK\City Navigator North America 2009 sitting on a network shared drive. This folder contains exactly the same files that the map file in c:\GARMIN contains.

When I installed and ran GMTK on my netbook, chose Restore, chose Custom Folder and pointed it at the long folder name it created, it tells me it can't find a backup there. So I pointed it at the map folder. It still says it can't find a backup.

What pathname did you end up with when you did the backup?

I did it 2 different ways using different maps to test.

1. I backed up using Custom to the other computer. I asked it to put the created file in D:\Garmin (over the network). After installing GMTK on the other computer, I requested a restore and entered the address D:\Garmin under Custom.

2. I backed up to a local drive, W:, on the originating computer. On the other computer I requested a restore using Custom and pointed to the GMTKbackup folder that GMTK had created on the networked W: drive (\\Terence\W:\GMTKbackup).

From looking at the created folder on the originating computer for the second process, it appears the backup does not compress anything but includes a file to guide the restore process.
