After recently buying a used xtrons 7.1 headunit, i wasn't 100% happy with the performance as sometimes it would lag and apps would crash the system, requiring a hard rest. this still presisted after using recovery tool to flash the stock rom, so after a couple of days researching room i choose Hal9k's rom, this made the rom a lot more stable with apps and there was an performace increase.

Additionlly in his rom there is more sound control options using Viper4andorid app this allows for more sound adjustment if you know what you're doing.

This also allows andorid 5.1 headunits to be upgraded to andorid 7.1.

if you intrested for doing this for yourself, heres a link to his post on the XDA Fourm where he provided a changelog of the rom and a how to guide on how to perform the rom swap and to check if your headunit is compatable.
