CR-V Retrofit Navi-Reciver connector problem

Hello community, I have now finally managed to expand the 6-fold CD changer and to plant a cheap 8-inch China-Navi (type PF71CHV) in my RE5. http://www.ebay.de/…/261216369442?… And as I expected, some plugs don’t fit. Power block fits, but Aux/Speaker doesn’t… Picture 1 are my plugs on CR-V, Picture 2 the cinch plugs that I have to adapt to it somehow. I would hate to solder, but would look for an adapter. Unfortunately, I couldn’t find anything in the widths of the network. Of course, if I didn’t use Cinch directly from the three Honda plugs, I’d be grey, white, green on the 24-pin plug that is sucked into the navigator… Does anyone have an idea for me? Edit: After a long time of searching this: I strongly assume that the white Honda plug goes to the speakers. Because for this there is an adapter on ISO, but there would be a lot to think of an adapter to the ISO.
