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

Different receivers handle ratty data differently. Depends on the degree of error wether or not your device determines it's postion is close enough to put you on a road. And remeber you're dealing with a constellation of 27 birds that depend on line of sight with your device. Lots of ways, including weather, to affect this negatively. My issue cleared up after I got out of the Columbus area. So who knows what the actual issue was.

 

I do cancel the scan when it comes up, but the device keeps connecting and disconnecting repeatedly, so it pops up multiple scan notifications over and over again so quickly that the only way to stop it is to disconnect it.

I'm using the cable from the box, but I'll try another one the next time I get through the house. Can't do it out here on the road, sometimes those updates are a couple gigs and cell data is insanely expensive nowadays. And forget about truck stop wifi, especially when there's 100 drivers trying to access it at once LOL.

If the new cable doesn't work, I'll try your suggestion on keeping the unit plugged in and restarting the PC. By the time I get back home, my new laptop will be in and it has Windows 7 on it instead, and maybe it won't be such a pain.

If I ever find the guy who decided to put Windows 8 on PCs and not just tablets...

 

Did you check the constellation status yesterday?

 

For anyone interested- a check of the GPS constellation status showed a couple of sats down yesterday for routine maintenance. With respect to Mark- been sitting here for 30 min googeling Blood Moon and electronics failures- da nada. 😟 Sorry Mark. Still looking though. Meanwhile, experiencing no gps reciever issues today.

 

That could be the problem, I was plugging it into a 3.0 port. My PC is an Alienware M14x, one of the cheaper models. It only has 3 USB ports, and I think two of them are 3.0 ports, and the only 2.0 port I have was being used by my Logitech wireless mouse, so maybe that's where the entire issue is. Never occurred to me to try the 2.0 port LOL.

I'll update on the thread here in a week or two when I can get back home to my high speed home internet. I don't wanna try updating on my cell data plan, because this is a new unit and probably needs quite a few map updates and such.

 

Having all kinds of sat issues with my 720 the last two days also. DOP is 60 and 0/11 sats found. Tried resetting, diagnostics and anything else I could think of. Help! No interference issues either. Been working perfectly until yesterday. now it's constantly telling me I'm off the road.

 

Same for me. RM had me about 1/10 mi east of I25 from Denver to Cheyenne. Android/google & Navigo/Maptuit both unaffected.
