    Before I continue, my current version on the 500 is 10.2.1472.1717

    Route Mode=GPS is following a route
    Follow Me Mode=GPS is not following a route

    Ok. While in Route mode, I see the pop-up warnings. However, in followme mode, while the icons are displayed ( for weight stations and state lines etc) no pop-up are displayed. Is this something RM is looking to change in the next software upgrade.

    Been out on the road a little over 20 years and more then not, use the 500 (or any GPS) in follow me mode for a reference and "early warning" tool rather then a tool for routing.

    In a "follow me Mode" the GPS knows where you are on a physical level on the map, but has no idea of where you are going. To give early "warnings" in a "follow me Mode" would mean the TND would give warnings for all directions since it has no idea of your direction.

    Let's say you are going West in a "follow me mode", you would expect the TND to understand that, but what it sees is different GPS locations on a map. If it tried to "understand" your direction then what happens when you change direction again?

    I will bring this up to RM.

    Thanks,
    Mark

    The externa antenna is the same for the TND 500 and the TND 700.

    Thanks,
    Mark

    It might work if it was to assume you were continuing on the road you were currently on and give warnings for whatever is ahead, but only by looking at the next 5 miles or so. It would only change roads if you made a turn. They could play with it and see what works without bogging down the unit.

    Hiya, TND 500 SN A35T5B170751 This thing is giving me fits. 4 calls to RM support for help and 4 different answers, none of them seem to help. After TND Dock update downloaded it tried to unpack/install and I get a corrupt file missing .msi file warning and the whole process stops there. Now I own a $499 paper weight, some help resolving this little issue would be appreciated.

    Have made sure anti virus is off, even uninstalled it, no effect.
    Tried plugging the unit into a different computer, no effect.
    Uninstalled TND Dock per agents instructions, now I can't get it to reinstall.
    Attempted to download TND Dock from RM website and same issue occurs.
    Manually deleted TND Dock files from my temp files and hard drive per agent instructions, no effect.....

    Last agent told me it may have to be returned to RM and told me he would speak to a supervisor and call me back, it's been 5 days since last contact, RM is yet to return the call.

    With respect, what you wrote makes very little sense to me.

    This GPS-any GPS device-works by creating a sphere based on computed sat data. The more sats the unit "sees" the more complete the sphere. As the unit moves. it is able to compute speed, direction and altitude as sat data changes. The unit-for lack of a better word-know's it's computed location (subject to SA) and if it is moving and what direction it is headed, and can compute the rate of the movement. The unit (depending on programming) can compare all of this data to that of a database and display the sum of all the data on a display screen. Comparing location data to that of other set location data (POIs, construction data etc) requires nothing more then a fast CPU to make all the rapid comparisons.

    In the not so old days-before moving map displays, all one could get was postion, rate, and elevation data. Which was great for boats, hikers and even avaition but lousy for driving.

    So to say that the unit cannot provide a pop-up alert because it doesn't ( again for lack of a better word) know is false. The TND500 already, in fact, displays both POI and other icons on the moving display in both modes-which is something you should be aware of-depending on the view level. It's lack of a pop-up alert in "follow me" mode is a programming decision, not a limitation of the device's capabilities or the GPS system as a whole. It's the software engineer's desire to weight the route mode over the simple follow-me mode. Nothing less and nothing more.

    A lot of drivers-including myself-do not need nor require routing. We pretty much already know where we are going and how to get there. What the unit does is provide a "head's up" for us. And that is what makes this a good tool-but not the end all.

    E-Mail me your name and phone number... RM will resolve it as soon as I get your Information. The system files are corrupt and the TND will have to be exchanged.

    But, if you have some time I can work with you on the phone. IF the NaviMaps are still good on the External SD card then I can get you up and running.

    Thanks,
    Mark

    The GPS antenna is a hardware item. It receives raw data from the Satellites and the Code will take this raw data and plot it on the map. The POI's showing on the Map are simply plotted points on a Map. It does not "sense" the upcoming POI's and display them. They are hardcoded already by Lat\long.

    What the piece that is missing is in the Code where it takes and "senses" your direction and thus makes a decsion. The Code has to "remember" your direction of travel. All the "follow me" mode is having is the GPS plot your location on a map.

    What is needed is code to be written to "sense" prior "plots" and based upon "prior" plots is to give an "estimate" of your direction.

    The Map and anything displayed on the map are already Hardcoded by Lat/Long. The only variable is your "plot" or point in time in relation to the map. Everything is Databased in the TND except for your physical Lat\Long.

    What the GPS does not "understand" is what direction you physically "want" to go. It is simply giving you Plots based upon your physically location. Detecting speed and such is based upon prior "points in time".

    What this can lead to is drivers having the TND tell them their is a weigh station ahead by "estimating" your route and the driver turning before the weigh station thus giving the indication that the TND is wrong. This "follow me" type of routing has its pros\cons. I have forwarded the information up to Rand.

    I think we both agree on how the GPS works, but the time\cost\feasibility of coding this type of "follow me" routing is also a key factor.

    Rand will most certainly look at this.

    Thanks,
    Mark

    I can agree with that but in my mind Mark, it's simpley a matter of proxcimity. The software should know where the unit is what, compare that information to the POI data points and do an alert based on the proxcimity of those POI to the unit. Thunit is already displaying the (for example) weigh station icon and nearby POI on the map screen illrelevent to operating mode. Would it not be possible to key a alert pop-up to these icons-after all, to be where they are on the map display, the unit already knows their data-points relevent to the unit.

    Anyhow, thanks for going to RM on this. I think they've made a great start here but they need to carry through.

    Off thread-I see there is a port for a traffic receiver. What are the plans for this and are they near future?
