Turn off kenwood
connect Pc and kenwood
turn on kenwood
turn on navigation and set to mass storage
p.s.
For text and voice i found solution but i forget to write here.
For Voice you must change name of your voice with name in kenwood voice folder that you will not use ( ex. If you don't need Greek voice you change name Slovenia.vpm to Greek.vpm and add in voice folder )
Then go to Radio settings ( NOT Garmin settings ) and turn off TTS and you can set text and voice for your country.
