Anyone have first hand experience with the IPod cable that Toyota sells for the Avalon? Seems that it only works if sat radio is not used. However, some info I have seen on it says that iit will not work with premium JBL radio because it has embedded XM radio. I have an 07 Avalon with the JBL radio and nav system. I don't think that this radio has the embedded XM but am unsure. This is a high priced cable and I don't want to get it and be sorry. Any info anyone may have about this accessory will be greatly appreciated.
