Rand McNally Support Thread. (Part 3)

Thanks for your reply! It does nothing because the Truck GPS splash screen is as far as it goes. That’s when it says Truck GPS isn’t responding. Only thing that works are actually more of the android functions.

 

Mark
I need to get with you on these files ASAP
i checked through all the past ones and i still don't see any mention as to what 2 files i need to send you and where they are exactly.
Some of my folders seem to be locked.

 

Mark, I am in need of your help sir. I have a TND 720 that I've had for several years now. The issue that I've had with it for a couple of years now is when you get to "working it" it will crash. I've sent it in twice now to be fixed and still have the issue. When you turn the unit on it takes it at least 10 mins to load the map. The unit will also now randomly crash running down the road. When this happens it also takes at least 10 mins to reload the map. It has always acted like it was running out of processor or ram. Today for the first time after it crashed I got a "system memory very low" warning. So it appears that my long held assumption is correct. I have a class 10 8gb SD card in it so the memory and speed there should not be an issue. I do however have 140 or so saved trails. But the issue started well before I had that many saved. I take it in the house every 2 months or so update it and run the diag/repair on it. it almost always finds something wrong. I actually paid attention this last time (about a month ago) to what file was actually broken. As I recall it was usergps.ini, I don't know of that helps at all.

 

Have a look at Post 3130 of Part 2 on the previous thread and see if that helps you any. Make sure your SD card is not HC as it will cause problems.It should only be a 8gb or 16gb, class 4-10, with a "C" around the class (number) on the card. If it is bigger than 16gb or has an "U" around the class it is the wrong card and will cause your issues.

 

I have some feedback for the TND 740...

After talking with tech support today for my issue of the Truck GPS not responding. It was a software issue and I had to invoke the android recovery tools. My frozen splash screen issue has been resolved. To do this on the TND 740, do the following:

1. Power off the unit
2. Press and hold the Home and Power buttons until the unit turns on
3. Select Android Recovery and press Volume Down button to launch
4. Wait for the dead android robot screen
5. Press and hold Home and Volume Down button and while holding those two, press Volume Up.

This should then load the screen with recovery options for the TND 740!

 

If there is an option there to delete the cache partition then I would suggest doing that,this seems to clear up some issues on my Android phone so should work on the tablet.

 

Thanks Mark, I might have found the problem. It looks like my card is a HC. I used to have a old class 2 2gb in it a couple of years ago and thought it being so slow was the problem. Here's a link to what I have in it currently:

I'm not Mark but I had the same problem with my TND-720 and changed the SD card to a standard one and it rectified my problems but now you would need to put in a new card and download the maps again and Mark will be able to help you to do that as your unit needs to be tricked into downloading the maps again. Not sure if this will work but worth a try. Uninstall the RAND Dock from your pc,put new card in unit and download a new dock from RM website and see if it offers you a new map download.
