After couple of days, after listening my music in car, i came to the conclusion that audio quality is the same as before update. So, i’ll stay with 0490 firmware. Ne need to downgrade.

I just updated the firmware from 0435 to 0490 (thak you, varooom ). I wanted to do this update in order to fix some issues about the quality of audio. I read in this forum for some audio improvements with the 0490 firmware. So, all process went straight forward, took about 35 min, engine on. After the update was installed, i checked and erase all errors with VCDS. First impression: everythig is the same as before, except the sound: Lower tones are more consistent, medium tone are the same but the big problem is: High frequency tones are too low. I think like 30% less than in 0435 firmware. At least this is what i felt from the moment i turned on music. Sometimes is like i don’t hear some sounds. I decided to stay with 0490 for a while but unfortunately for me this lack of treble sounds is a no go. It is possible to downgrade to 0435 ? Thank you.

Yeah, i know this is the last version. Thank you!

Hello! Can anyone help me with the firmware update of my Amundsen MIB1 from a Skoda Octavia Scout 2015? I attached a photo of my actual firmware. Thank you in advance for help!
