Murata Radio ROM problem - sound mute

[VictorC666]

Hello,
I've just updated my polaris radio to Murata PPAS 1.58.21.23 two day ago, after that, i have strange problem, sometimes sound is totaly mute and only soft reset helps. Could it be because of Murata PPAS rom upgrade? No problems before with original radio rom.
Thanx. VicC
