Possible po ba to use the Navigation without the radio? - how?
Generally speaking, most HU will allow you to do that. Check the manual.
In many cases, there's a dedicated button for it called "Nav". You can turn off the radio (or put it on standby) and then access the navigation by pressing the Nav button or choosing it from the menu.
What's the model of the AVT?
The last AVT I used was a dealer add-on on our 2010 Tucson. We sold the car already but I do remember that with the radio off or your input source selection set to an unused input (like Aux 1 or 2, Bluetooth, SD card, etc.), you just press the NAV button and it'll bring up the navigation screen.
On my Kenwood DDX8034BT, it's the same thing. Set input to something that is unused or Standby. Then access the NAV features by tapping it on-screen or through the remote.
