    Default GPSMap 62s doesn't display route turns

    Hi All,
    I've searched around garmins forums but haven't seen a mention of this problem.

    If I create a route for cycling in mapsource or memorymap and save that route as a GPX on my 62s, then find route and select, the unit will calculate the route, and as i cycle each turn will turn the display on for 30secs and give a chirp.

    If I use send to gps, that same route to gps using mapsource or basecamp, all seems the same until you ride the route.
    The unit doesn't awake at turn points and chirp, you can actually pass turns. If i press a key to wake the display, the turn arrow is there, it's just not doing the auto prompting.

    Anyone seen this or know the solution, other than save as gpx instead of send to..

    Regards
    Dave

    Does your unit recalculate route in the second way?
    If yes it is very strange because gpx file are equal in both case!

    Perhaps this will explain the behavior of the device.

    Hi Both,
    thanks for the replies.

    After reading the translated text, i think i will just "save as gpx" and let the unit calculate from now on.
    I know Giomen said the gpx were the same, but clearly (if i understood that german post correctly) basecamp calculated routes are handed differently.

    Any Garmin device recalculate uploaded routes before to use and its do it on your own SW algorithm. It is fact!

    Not all Garmins re-calculate an uploaded route file (.gpx) from Basecamp.
    Nuvis with trip manager (like my 3490) don't.
    What would then be the benefit of Basecamp having so many adjustable driving profiles, if not to have exactly the same route in the device.
    When I upload the simplest route (Start->Finish) to my 3490, the gpx contains also a lot of "basecamp's intermediate route points" for every turn and direction changed, according to the profile I've chosen and the custom changes I've made to this profile.
    Notice that all maps don't react the same when using the same profile (more in the example below).
    When you upload a Basecamp route, the trip manager in the device shows the route exactly as it was in Basecamp.
    When you start routing this route it doesn't prompt you for re-caclulation, the routing just starts and it follows the roads in Basecamp.
    BUT if in trip manager, you change someting in the uploaded route (like the order of route's points) then and only then the Nuvi re-calculates the entire uploaded route using its SW and its routing rules and avoidances. If you reverse the changes (order of points) as in the original uploaded route, the Nuvi re-calculates the route again, so the original uploaded route is lost for ever.
    Even if I calculated a route in Basecamp with one map and I use the uploaded route with another map for the same area that has the same roads in the same places on the map (doesn't matter the road category as long as there road-lines in both maps) the Nuvi won't re-calculate the uploaded route.
    If I am not at the starting point of the uploaded route (as in the example below) and I choose to navigate the uploaded route, 3490 will use its SW and rules to calculate a route to the Starting point of the uploaded route and then use exactly the Basecamp's uploaded route to the Finishing point!!!

    Maybe its different in handheld Garmins, I remember to have the same issue with a new eTrex Touch, maybe it's a bug in their SW.


    Spoiler: EXAMPLE
    Two maps covering the same area, CNEUNTU 2017.1 and Autodrive 4.50
    A simple route with just a Start and a Finish clicked on the map.
    The same Basecamp profile, Off Roading and Route Preferences set to Shorter Distance and in Road Type Avoidances only Unpaved Road left unchecked.
    Nuvi 3490 set to Faster Time and in Avoidances, only Unpaved Roads checked (3490's SW tends to use the bigger-faster roads this way).
    First thing to notice is that Autodrive applies the Off Roading profile much better than CN, that has the same unpaved roads but uses mostly paved roads (whatever I've changed in the profile, I couldn't make the CN to create an Off Road route like Autodrive).

    CN and the red route that uses mostly paved roads, although there are many dirt roads that are "shorter distance" (as the profile is set).
    cn


    Autodrive and the blue route that is correct, according to the Off Roading profile.

    3490 with Autodrive map and blue route (created in Basecamp using Autodrive map)
    Notice that the time for the uploaded route is different than in Basecamp, because in Basecamp I've changed the average speeds of the roads, something I can't do in 3490, which calculates the time (not the route) according to its SW and the map speed limits.
    3490 starts the routing immediately after I press GO. The route is exactly the same as in Basecamp, although the 3490's SW is set to avoid all Dirt Roads and to calculate the Faster Time.
    3490ad1



    3490 with CNEUNTU 2017.1 and the red route (created in Basecamp using CNEUNTU 2017.1 map)
    Again the time for the uploaded route is different than in Basecamp and also different from Autodrive's, because each map has different speed limits for its roads.
    3490CN1



    3490 with Autodrive map and red route (created in Basecamp using CNEUNTU 2017.1 map)
    Even using a different map than the one the route was created with, 3490 does not re-calculate the uploaded route because there are roads from where the route is passing. Maybe it would re-calculate using its SW if some roads were missing in this map.
    3490CN2



    3490 with Autodrive map and CHANGED blue route
    When I go to the trip manager and change something in the uploaded route, like the order of the points and press SAVE, 3490 now recalculates the whole route from the beginning, according to its own SW rules and avoidances.
    Even if I change back the order of the route points, as they were in the uploaded route, again the re-calculation is done by 3490 rules and I loose forever the original uploaded route.
    Now 3490's route uses only paved roads.
