  • Notifications are too late

    Eversince I changed from my laptop to a Via Epia system (SP12000) the verbal and visual notifications in MapMonkey are too late. For example, MM says "Gatso in 500 meters" while the gatso is less than 350 meters away. The last warning "aproaching gatso" always comes after I passed the Gatso, usually 50-100 meters after. The same goes for directions, they also are about 50-100 meters too late.

    Also the speed MM shows is way off compared to my car's speedometer. (+-15km.)

    I use a BU-303 in the back of my car, just behind the rear window. Usually it sees 6-8 satellites. I've tried putting it on the roof, but with the same result. (although more satellites 7-11.)

    What can I do to get more accurate positioning?

    I have the same problem with late reporting of Gatsos. It's better with directions - maybe map monkey is 'looking ahead' more intelligently with the directions.The GPS speedo is probably more accurate than the cars one though it will suffer from latency and update delay etc.

      Not sure how to get better positioning, but you can always change the distance settings for camera warnings to give you more warning...

        Mark,

        I am building a system using a M10K and was wondering if you have any problems with it announcing turns etc. late?

        I have only tried D3/MM on my laptop so far and the voice messages were pretty good with that. I'm concerned that the M10K might be underpowered for this application?

          I would tell you m8, but I still haven't had time to look at it to fathom out why I can't get a video signal from my system.

          Up until yesterday I was running a ghetto system consisting of a laptop in the passenger footwell....

          BUT..some MOFO smashed my side window and stole it while it was parked on the drive.


          The laptop was old, a Celeron 566 iirc and that was late with positioning on the map and gatso announcements. I'm hoping the M10k will be OK once sorted...I need to sort a lead for the Xenarc too as they took that (it's no funking use to them as they left the screen)...

          I know when I used Viamichelin, it seemed to position me better on the map and update quicker even on the laptop...

            the only thing I can think of is that you have set your baud rate for your gps unit lower than what it was set before, this would cause a delay in your position, which would make everything in MM and FD appear lagged. Try running your gps unit at a high baud rate.

              Does it matter on which Baud Rate it is? It's currently at 4800 * but I can choose from a big range, going from 2400 to 57600. (* If I recall correctly it also was on 4800 with my laptop.)

                I've changed the baud rate to 9600 and it didn't get any better.

                  Changing the baud rate to anything over 4800 will have no impact on the data transfer since most of the GPS receivers transmit only up to 4800.

                    Try enabling "WAAS/EGNOS" using the GPSInfo program. According the user's guide it will increase the accuracy of positioning

                      Ah I didn't know that, no wonder it makes no difference...
