well, thanx guys for help.

the latest is I got the E815 and it is working, even it is getting charged when using the cradle, I went back and tried to charge v710 it did not charge, the v 710 is working well with my MB E55 equipment.

the BT system working good with the E815, but I am having another issue here, I am able to recieve and make phone calls, the other party can hear me but I can not hear them, initially I was able to talk and listen, I am trying to figure out what went wrong today, the system was working well yesterday
