  • Importing custom POI's

    I'm not aware of the POI Converter software but it may be it that is taking the POI name and forcing it down to old IBM computer standard with an 8 character size limit.

    I'd suggest you give Extra POI Editor a shot as I haven't heard of this problem using it to convert OV2 to CSV files. You can find EPE at

    If that doesn't work and you don't get any more response here, I'd try where there are a lot of POI experts (many of them members here as well ;) )
  • Changing route(s)

    The 3597 uses via points as destinations by default but it's more than simple to change them to shaping points if you are using trip planner. Just load your trip and the list of via points screen appears on the screen that has the Map and GO icons on it. Tap the "FLAG" to the left of any of the waypoints between the starting point and the end point and the Nuvi will ask you if you want to change the waypoint to a shaping point. Say yes and your good to go.
  • Is there an alternative for Garmin Basecamp? is an online trip/route creating site which creates gpx files that can be downloaded as Trips to your GPS.
  • What awesome places has your GPS taken you?

    A couple of years ago, took the 15 hour ferry ride from Port Hardy, BC, on the Vancouver Island, to Prince Rupert, BC through the inland passage. Spectacular trip, especially with the Nuvi keeping track of where we were.

  • Is there an alternative for Garmin Basecamp?

    I'm finding a few issues with the new version of Tyre. Can't seem to recalc a route after a reorder of waypoints, for one. Will forward issues to them as they seen to want to correct all found issues quickly. Version 7.01 and 7.02 have already been released.
  • CN NA 2017.30

    Yes, over a 6GB download but that's all types of maps - road, 3D, DEM, JCV, plus Voice Recognition, etc. and the downloaded map data isn't compressed which is part of the work done on your computer prior to the transfer to the GPS.

    Borrowing from a post alandb made on another site, the files installed on a 3597 look like this:

    9,949,184 d3397200a.db (replaces d3397190a.db)

    More like 3 to 4GB of data installed on the Nuvi.

    What I noticed after installing the device software update and then downloading the map update was:

    - GE initially crapped out and reported an error that it couldn't download the update
    - MapUpdater downloaded about 65% of the update and then went back to 50% before continuing to completion
    - MapUpdater reported it has successfully installed the maps on to the device (which it had) but that could not install them to may computer except the files are on my computer and work fine in BaseCamp.
