I have tried all types of combinations regarding the buttons around the unit and none of them take me out of the Navi screen.
There is one thing i haven't tried yet is using the remote control unit to exit, i'll try that tonight and see if it might work.

Boki_Srb, can you let me know where i can find this ''package adapted to such device. Primo ESX 9.6.5.278914.''
A direct link would be greatly appreciated.
Thanks
