Radio GTmedia D2 fault in system setup

[jankomix]

Program version: "SW version D2- 19613a DAB SDK v0.5.8 r9867 "
Inside menu system setup fixed: brightness, timeout (display always on), time format 12/24 are active only after seting. When radio is off
and switch on again the setup is as before seting. Moreover the volume after switch on is high !
Is it possible to upgrade this firmware for correction thees bugs ? Radio is very interesting in my collection, but listening it with display always
on full consumpts battery too fast.
