Update: see post #23 for solution to Mute Level non-functional.
After installing the Z140 upgrade on my Z110 (which was running Z130 s/w), I thought all went well. This morning, I noticed the volume didn't lower when I pressed the VR button to enter voice commands to my iPod. So I manually lowered the volume and spoke the command - which worked as usual - then manually raised the volume to a normal level. So VR works - just no attenuation.
While sitting at a stop light, I checked the AV System Settings menu to see if my previous selection got turned off during the upgrade. Although the [Mute] setting was still Guide/Tel/VR, the [Mute Level] button next to it was greyed out and did not display any setting. Pressing [Mute Level] should cycle between 20dB, 10dB, or All. But it had no effect. According to the Z140 manual (pg 180), this setting "is not available when AV source is Off". The unit is behaving as if the AV source is Off, even though it is playing my iPod source.
I tried doing factory reset, still [Mute Level] is inoperable.
Has anyone else seen this problem???? It seems wierd that only this feature/option got disabled. I wonder if it is related to the fact that the files posted were actually for Z130 hardware upgrade. Pioneer has a different upgrade product for Z110-Z120 hardware. However others have upgraded Z120s and not reported any problems. Maybe they just haven't noticed the problem?
So is this a general issue with the upgrade, or just some fluke related to my upgrade? I consider loosing the Level Attenuation feature a "show-stopper", and would definitely not recommend upgrading a Z110/Z120 with this software until this issue is resolved.
I don't suppose I could just reload my old software - go back to the Z130 version??? Looks like PRG1 is still the old stuff. Could just set PRG.FLG, but I don't know if the NDATA will match.
