Thanks for that Swing.. I have lots of Locatio.n and Minor.ve artNumbe.r0 items which dont make sense. I cannot get a screenshot to post in here to show you. Unless its easy and I cannot see it.

Thanks MaFt for helping me understand better about the category / sub-category thing.
Also many thanks for all your hard work on the POI's :D

There's another thread on here regarding the POI problem - apparently one suggestion is to simply leave the unit - the person said it took 2-3 minutes on the first bootup, but has been quicker ever since (makes sense from my understanding of how the Garmin file structure works).

Failing that, if the unit is completely stuck, I might have an idea of something that may fix the problem, but would prefer to see people try the above fix first.

I have been reading the forum with interest on the problems some owners of the Nuvi 660 have been experiencing with their units and hope my experience with my Nuvi 610 will be of interest if not helpful.

I purchased a new Garmin Nuvi 610 just before Christmas, which as it turned out had corrupt files in the Garmin folder. I only found out about the problem when I connected the 610 to the Garmin web site in order to update the software from v2.30 to 2.70. The automatic update failed and so did trying to carry out the update manually by downloading v2.70 to my PC and carrying out a local update.

Fortunately before trying to update my 610 I had taken a complete backup of my 610 files by connecting it to my PC via the USB connection and copying all the files and folders to my PC, which I then burned to CD. By the way, one of the files is a hidden file, so if you decide to backup the files from your Nuvi, you need to make sure Explorer has show System and Hidden files switched on.

It turned out I had 3 corrupt files which would not delete when I tried to remove them with Windows Explorer. Although it appeared the files had been deleted, when I exited the folder and re-entered it again, the file names reappeared, but with a file length of 0 bytes. Even using a file unlocking utility "Process Explorer" which goes down to file handle level I still was unable to remove the file names. As the Garmin 610 is effectively a drive when connected to the PC, I decide to perform a quick format on the 610, which removed the corrupt file names along with everything else. I then used my backup to copy all the files back to the 610 except for the corrupt files and ran the v2.70 update utility from my PC. This time the update went without any problems and my 610 is now running v2.70 software.

Since updating to v2.70, I have downloaded the latest POIs from the MaFt and PocketGPSworld web site, plus the PocketGPSworld speed camera POIs. I combined all the POIs into one POI file which via the Garmin POI Loader I copied onto my 610 without any problems and they all appeared OK.

I have also experimented and found out you do not have to combine all the POIs into one large POI file. Using the Garmin POI Loader I transferred the MaFt POIs to my 610, then using Explorer I went to the Garmin/POI folder and renamed the poi.gpi file to MaFt.gpi. I then repeated the same exercise for the PocketGPSworld POI file which I renamed to (you guessed) PocketGPS.gpi and the Speed camera POI file which I renamed to SpeedCameras.gpi. My 610 recognises all the POIs as if they were in a single POI file, but it means future updates can be carried out to the individual files instead of to a single all encompassing POI file. In future I only need to copy the relevant POI file to the POI folder, delete the original and rename the new POI file to replace it.

One last point, in messing about (serious investigative study and familiarisation practice) with my 610 I ended up with the Favourites folder completely filled with locations. The daunting thought of having to remove them all one by one (why didn't Garmin make available a remove all option) did not appeal to me. I found out the easy way to clear out the favourites folder was to delete the "current.gpx" file from the Garmin/GPX folder and replace it with the original file from my CD backup.

If there is one piece of advice I can offer to anyone, it is make sure you take a full backup of you Nuvi GPS. I will be doing just that before and after every update to my Nuvi operating software. It takes less than 10 minutes and can save hours of heart ache at a later date.

Finally (I am almost finished, honest :-0 ). I have put together a Excel spreadsheet which enables me to calculate the time/distance settings verses speed for when I want to change the default settings in the speed Camera CSV files. If anyone is interested, I will place a copy on the forum.

Hi Louie7, really good post, learned some good points, and confirmed some suspicions. I for one would be very grateful for you spreadsheet.
