Hello, my name is***** sounds like the system is locked out by the security system. When battery power is lost this will occur. If you have the code to turn it off it will typically be in the glove box and will be on a small card in the vehicles manual. You should see if you have this code. If you do then you can enter it into the nav system to get it working again. If not then you will need to go to the dealer to have this done. If you need more help please let me know.
