Hey guys. I've recently bought a pioneer F9210BT for my WV Golf mk5, i've installed it. and everything seems to be working. But when i connect my phone with the parrot ( BT ) device on the 9210BT and make a phone call. I get no voice but the other end can hear me, same thing happens when navigating. The usual annoying voice won't direct me. Is this a known problem or just my failure on the connection of wires? Thanks for you help in advance.
