The firmware version r404M for G90 (A7LA70 version) introduces and improved audio recording, more choice of video resolutions and the LDWS feature.According to the manufacturer, this version bring further improvement to the sound recording quality.
The problem seems almost gone now. With the same noise level as tested before, if there's any saturation, I could hardly detect anything.
There are also more resolutions to choose from, like 2560x1080@30fps, 2304x1296@30fps and a 1920x1080x60fps.
(Note: these fps values are for NTSC mode, in PAL they become 25fps and 50fps)
A7LA30: 1920*1080p/30fps
A7LA50: 2560*1080p/30fps, 2304*1296p/30fps With FCWS,LDWS function, and the FCMD&LLW function will come true in near future(now is under researching).
A7LA70: 1920*1080p/60fps, 2560*1080p/30fps, 2304*1296p/30fps With FCWS,LDWS function, and the FCMD&LLW function will come true in near future(now is under researching).
After a quick test with the "A7LA70 edition", the 2560x1080@30fps mode gives a real improvement to the video and 1920x1080x60fps records perfectly. Playing back with such a high frame rate is choppy on PC but plays smoothly on the device itself.

The LDWS feature, namely Lane Departure Warning System is supposed to warn the driver when he drifts away from his lane.
While not visible in the settings, some other features announced here are possibly activated in r404M, the FCWS (Forward Collision Warning System) & FCMD (Front Car Moving Detection): During my short test today, I could see a red flashing warning message "Frontal Car" appearing randomly on screen (even with clear way in front of me).
Small bug: The "Volume" controls are inverted: right arrow for "down", left arrow for "up".
