Well! I can confirm I don't have the software version menu on my unit... I then used my can tool to harvest what I could (see pictures)
For the rest under the Ecu menu of the radio, I saw that I had no history of "reprogrammation" of the radio, could it mean that my unit, just never got updated?
Anyway I'll try to get that issue taken care of under the warranty to the Renault garage where I purchased the car!
Okay, I assumed you didn't have warranty, in that case going to the garage would probably be the most sensible idea.
I hope that they'll find and solve the issue soon!
