Downloaded new update now GPS will not work at all!

Need details... What's not working? The unit doesn't boot up or you can't route because it says your map files are expired?
If it says your map file are expired, you will have to call Ray Allen @ RM Tech Support at 877-446-4863 and have them email you a new navigation.lic file.
It goes in the navi/user folder and reboot. reconnect to computer and delete the bin and layout folders, reboot, reconnect to dock and update it via the TND Dock software.
If that does not work, they will have to send you an SD memory card with a new program on it to install into the TND 500. This will erase EVERYTHING and restore to an "out of the box" condition.

When i push to calculate route the screen gets stuck on "calculating" and won't do anything.

You have a corrupted trip.db file.

1. connect the TND to the computer and turn the TND on.
2. go to your start menu and press on (my) computer
3. look for an external drive called intelliroute.
4. look on the drive(s) for a folder called Navi
5. double click on the Navi folder.
6. You should see a folder called User.
7. double click on the user folder.
8. You should see a file called Trip.db.
9. left click once on trip.db, then right click and delete.
10. disconnect your TND from the computer and enter a route in.

it should operate fine now.

Check engine light code tcc 740

A tcc 740 is a code for a torque converter clutch problem. This is either the torque converter itself or the control part of the TCC system. dodge's have an issue with transmissions of this generation and in most cases when the code 740 sets, the transmission will need to be replaced.-------
This will help. Thanks please keep updated.please please do rate the solution positively .thank you for using fixya
