Switching from RNEG (Myway) to RT6 (Emyway) - only Slovenian language :(

Hi and a good new year to everyone! I’ve got the following issue:

I have a year 2012 Peugeot 308CC, formerly equipped with VIP Nav RNEG, and now bought a VIP Nav + (RNEG2, RT6) with its high resolution screen on eBay to install it in my car as an upgrade. :)))

The installation of the radio and the screen so far was done by a local Peugeot garage, and the new radio works ok, except the language which is now in Slovenian (!) . It seems that it cannot be changed to any other language..:beating:

Any ideas what to do? Thank you very much !
