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

Same here, I like driving the ditches they are smoother then I 65 sb in.

so what's up with the GPS satellite to day ?

 

no sat problems in CA

 

Is anyone having a problem with the TND 720 not connecting to a PC correctly?

I bought a new one at MATS and am trying to update it. When I connect it to my PC, the unit itself shows it's connected, but in Windows it keeps connecting and disconnecting constantly, popping up windows asking me to "Scan and Fix This Drive". I can't even get the Dock software to install because of this.

This is the second TND 720 unit that I've had this issue with. The first one is sitting right next to me on my desk, completely dead after I chose to "Scan and Fix" last time and it refused to start up completely. Mark here on this thread worked with me on this back last year, and even he wasn't able to get it to respond, and he tried for a LONG time, so I know it was beyond screwed.

Why are these units having this issue?? I know it's not my PC because this is a completely different computer and operating system than the one I was using when my original unit died (Windows 8.1 on this PC). It's like it's impossible to update the units without going through a massive hassle. I can't install the dock software without a unit connected, and I can't connect the unit for more than 2 or 3 seconds because Windows insists that I need to scan and fix it.

Has anyone else had this issue and been able to solve it?

 

I had that problem recently- for me, turned out to be a bad USB cable. Make sure your USB drivers are updated and try another USB cable. That there is the limit of my knowledge- sure Mark can help you further.

 

I just cancel the scan and fix window and it always goes away then it works as normal

 

i was way off the road...had to mute the gps because it kept trying to recalc form side roads. Same area, 65 sb. Its not the sats though because my car gps and my qualcome both were on track. also lat/long listed on randmc put me right on the road when typed into google maps.

 

Mark, regarding the USB cable....

There is in the truckstops, a "universal" USB cable being sold. I don't recommend that this thing be used- has replaceable ends that aren't real tight. If you guys need a new usb cable, better luck with one that is not "universal" and is purpose built.

 

Don't quote me on this, most car Built in systems are NAV systems with GPS, it's tided to the steering wheel Engel and speed sensor of the vehicle, they can look at 5 to 7 satellites at one time.
