Hi there,

I have recently installed Grom with flash and aux(with charger) options for my volvo s80 2004

It is an excellent piece of device although it won't charge my LG G4 good enough even my screen is off, I only use soundcloud and I understand it takes some battery while using it.

I plug my phone normally via flash cable so I can use steering wheel buttons but still it won't charge any % while I am using it same for aux charger.

Do you have similar issue? I am looking to solve this problem, I was thinking about a 'usb triangle' like the connector where I could connect my phone to flash cable and my in car charger (12V, 2 A) so I can charge properly and play via flash, is that possible to charge at same time and play? Basically I need 'micro usb to usb male + usb male' but couldn't find anything on google.

Regards
