Hey Mark,

First off let me say thanks for helping all these people on here.

Hopefully you can assist me with my issue as well.

I have a tnd 720 w/ the 24gig SD card map update, has been running great for 3 years.

I recently updated it today (03/20/16) and when it boots up, it gives me the "serious navi error" message and times out on loading. ("Gave up waiting for main navigation engine"

Now I took the the SD card out to see if it would boot up without it and it did.

Powered it off, reinserted the card then powered it back on.

Same navi error preventing boot up, everytime.

I ran the diagnostic & repair on the dock app, it repaired some files.

after that i tried the boot it, same navi error,.

But again, removing the SD card, the unit boots.

So I'm guessing the data on the SD card is corrupt but I can't find where I can redownload it on the dock app. it says my unit is up to date, even when I removed the data from the SD card and put a clean one back in the unit. But I copied that data to my desktop just in case.

Any light you can shine on this for me will be well recieved, I love my 720, it's been a real trooper and would hate to go back to using the vanilia version

I thought a 16gig card was the max it would read without issues. Not to mention it cant be a "Ultra" card

I've been running in on a 32gig with no problems until now

I made a typo, its a 3.89gig update not 24 lol

Mark on the 760 Issue , it is really not a cable issue. Yes the cables will not connect to the new OBD 2 but the unit itself will not read the higher 500K that the new trucks are putting out.) the unit makes a bunch of lights go on the dash and drops a couple gauges down to the bottom. One of their techs actually told me that I could splice it to the wires behind the fuse box but couldn't provide a schematic of how that should be done.
That would have been the absolute worse thing to do and I could t believe they suggested it.

Internally the cable will adapt. RM is working with the different manufactures to resolve this.

Thanks,
Mark

The SD Card should be either a 8/16 GB.. Do not use the 32gb. They write data differently.

DO not use the Ultra/Ultra Plus/EVO/EMTEC.. These are considered an "ultra" card.

If the class has a "U" under it then do not use.

You will get different issues with the above cards. Cannot route, Dock cannot read, etc.

I posted an PDF to do an MD5, if you suspect your SD Card is having issues or just want to check the files on your external SD card run it and PM so you can send me the MD5 file so I can compare it to a base file.

Thanks,
Mark

Why does my tablet randomly restart and then have the date set to 1970?

and why oh why can't it give two practical routes when I compare. I mean 400 miles versus 700. Really

Humm.. that is a computer default date. Where are you seeing the Date? And the restart, is it the tablet or the Truck GPS app?

When you compare, do you use the option to compare based upon your settings?

Thanks,
mark

I have a tnd 720 w/ the 4gig map update, has been running great for 3 years.

**Update** After Uninstalling the dock software and reinstalling it to a different drive, the map update button showed up on the new dock install.

The device boots properly now with no problems.

There is an easier way. What kind of SD Card are you using?

Thanks,

The tablet. It may not always be a random restart but occasionally a drained battery. Today I think it randomly shut off, I started it back up and date and time were wrong, changed it in the tablet settings but still wasn't right on the truck GPS, restarted again and was back to normal. Happened to me more than once. Really frustrating when I count on this thing to track mileage and I have to restart it too often while rolling.

And yes comparing routes based on my preferences, which I will look at again but I'm pretty sure I allow all

What do you use for the DC Source? On the tablet under settings you can see a battery graph. When connected to a power source the charge should be increasing. If it shows decreasing then you are not getting the proper power.

Do not use the USB/DC adapters, even rated at 2.4 a, the tablet will not charge properly.

Does it do the same on the USB port on the tablet and the slice?

What model is it? the 70 or 80?

Thanks,
mark

lester · Mar 21, 2016

Sorry I should have specified, I'm not having charging problems, other than me unplugging it.
