Touch Pro 2 AV Help!!!!!!!!!!!!!

[DJMatthews33]

So I am absolutely stuck and hoping one of you genuises out there may be able to offer some assistance. I just installed a new Car Stereo it is a VR3 VRVD640g, It has a 4 inch screen and what i thought to be a phono A/V inputs. I recieved my touch Pro 2 TV out cable and it works flawlessly on my big screen. Turns out the input for the stereo is 2, 3.5 mm female ports one for audio and one for video. My hope was to be able to watch my slingbox on my screen. Now heres what I have done to try to fix the problem (1) Searched Tirelessly for a video phono to 3.5 mm (3 ring video style) adaptor because the audio adaptor is easily found (2) i tried an ipod a/v cable using double female couplers and plugging the cable into the single video 3.5 port, this yielded a incredibly distorted picture and no sound. If anyone can help I am actually a sprint rep....so if there is anything you need I can try to hook you up.......Thank you all in advance for any assistance you can offer!
