Looking forward to getting great info here. Purchased a 2008 HDPNA with 32,000 miles. Bike is in great shape. I also own a 1999 Valkyrie Interstate with over 110,000 miles. I've put about 600 miles on the GL so far and love it. The previous owner did not use the AUX function. Not knowing any better, I purchased the cable so I can use my IPOD and unplugged what was already there. I now can't hear the Navigation system. Does anyone make a splitter or is there another way I can have both work? Any help is greatly appreciated.
