igo9.6.29.636868 mute

hello. no sound on my igo9.6.29.636868 installed on 2din chinese. when i install it on a samsung tablet. it works wonderfully. should i modify my sys.txt?
THANK YOU

its not a sys txt problem.
search on your 2din for navi sound in the navi settings or in radio system settings.

delete in the navi SAVE map the profiles 01 lines.
then startup the igo on your 2din.

hello.thanks for your support
I did not understand :"delete in the navi SAVE map the profiles 01 lines.
then startup the igo on your 2din."

install a new android iGO.
it works oke.
