My RNS has the maps stored on the HDD but how can I see what version they are? How can I also check the firmware version of the unit?

The information about maps and firmware is stored in the service menu, which is only available if the RNS has been modified to have this menu enabled. This can be done with VCDS.

This can be done with VCDS.

Give us a clue!

1. Go to Navigation - 37

2. Click on Adaptation - 10

3. Type 50 into the channel box.

4. Change the value from 0 to 1

5. Click on test and press code

6. Exit out of VCDS.

7. Press <> and brightness to reboot the rns-510.

8. Then press setup for about 20 to 30 seconds to enable the secret menu (just keep your finger on it it will go from normal menu to radio then after about 10-15 secs to the hidden menu)

Enjoy!
