Suppport Thread for the TND 500, TND 700 or future Rand McNally products.

My GPS kept showing my truck off of route (in the woods) for a good hour today and it started working again. Any ideas? It's a 510

 

What time? I'm wondering if it was something atmospheric....stranger things have happened.

My I-20 issues were basically early this afternoon...from say noonish on.

 

About the same time

 

Hmmmm.......interesting....

 

Rand lost its mind today just west of vail pass. Garmin knew where it was just fine but rand had to have the route canceled after hearing please proceed to the highlighted route




Went on for miles signal showed 6 of seven satellites

Garmin sitting beside it was dead on

 

Mine did the same yesterday. I have a friend that had the same problem. I call conspiracy to get the latest version.

Should be latest version as its the 720 I think it had something to do with signal as there where canyon walls on both sides the rand is a lot weaker GPS strength then the garmin most of the time anyways

 

ok this is the problum i'm having with my 720

when i used my 710 and i hooked up the real time traffic antenna my 710 would charge (green light) all the time and when i was in a area that had traffic the real time traffic would work...

my 720 when the real time traffic is hooked up i only get the green light when it's in night mode, during the day the charge light is off or red or flickers red/green (ac charger not as much and dc charger) real time traffic will not work at all unless i unplug the charger from the power source wait until the 720 screen changes to ask if i want to run on battery power" i tap yes then plug the power back in then the real time traffic will work for 30 min to 2hr's..... when the real time traffic is not working the 720 saids "the real time traffic is DISCONNECTED"

it is my opinion that the chargers both ac and dc are not putting out enough power to run the 720 with real time traffic in day mode

also the sunshade for the 710 doesn't fit will on the 720.... the sunshade needs to be about 3/8 in wider and also needs a cutout where the power button is to make it easier to turn off
