Support Thread for the TND 500, TND 700 or future Rand McNally products. (part two)

I am pretty savvy please give me the path. What do you mean "force" the update? Thanks.

 

Force it with a hammer, lol

 

Thx. Will try that here shortly.

 

Force the usb port? I've got to wonder why it won't work without it?

 

So here is my story.
My wife and I both have TND-720's but as I am not working at the present I don't need mine but want to keep it up to date for when my wife's crashes, and it will at some point in time. I have been running into Navi.exe errors, scrambled maps, and telling me my license has expired. I have uninstalled the dock several times and also just deleted the cache file. Previous to last attempt when I hook up to dock it tells me map update and regular update available so I do map first then regular. I then do a diag. and repair and comes back with 133 bad files so fix them then the dock tells me there is still a map update so I do it. Then I try to run a route but either get the dreaded Navi.exe or unit boots but maps are scrambled or unit won't respond.
So now what I have found is that when trying to do a clean update after deleting dock is that the unit starts out at V-2428 after doing map update it goes to V-3590 then when I do the reg update it goes back to V-2428.
Last night thought would give it one more try before turfing it in the trash so started with new dock, did the reg update first then map update, did diag and repair and it only found 9 files but when finished it STILL showed map update avail but didn't do it, tried the unit out and seemed to work and stayed on V-3593.
The map update that's still avail says it's only 4 files but I'm leery of doing it cause if it screws the unit up again I would have to start all over and I am already getting to the point of scrapping it. Just downloaded remaining map update but did not install, checked my cache folder and the 4 files that were added were- Upload, BadPurchased.dat, INFO and PurchasedManifest.xml could any of these screw up the works????

 

Mine seems to b working fine after starting out with a new dock and updating the software first, which seems to be for V-2428 then updating the maps which brings it to V-3593. The only reason I downloaded the remaining map update was to find out what those 4 files were but now the dock wants me to install them which I don't want to do right now but when the new version map update is available it may not show unless I can delete those 4 files safely or just something within those files that may b causing a problem so that the dock will only show the new version update and doesn't install those 4 files.
BTW-what version will the new maps be???
