I've been looking into Bluetooth solutions for my 2007 and am having real problems using a GROM(my 2006 had no issues with the GROM.) When I go to Crutchfield to examine replacing the HU-650 I get a lot of warnings about having to rewire the speakers due to the amplifier under the passenger seat. When attempting to install the GROM I noticed the back of the HU-650 has two circular plugs, one for a CD changer and the other one I think is for the amplifier(has less pins than the CD changer.) There is nothing plugged into the either of those plugs on the HU-650. I know I don't have the CD changer but seeing there is no other plug back there does that also mean I do not have an amplifier?
Thanks
