I just bought a 2010 V70 wagon and I'm trying to figure out all the changes necessary to upgrade to the Dynaudio system. First, I have a Single CD High Performance Sound radio, but I'm somewhat confused about the USB and Aux connections in the console. I tried to play music from my iPhone and it did not recognize it. I ordered a lightning to aux cable to try the aux input. From OEM site, I see there are 2 radio options. I will have to remove the radio to confirm the part number. I believe there may be special parts to make the iPod work. The most important question is can I use the dynaudio speakers with either of these head units? And these Chassis numbers drive me crazy. These numbers below are completely different than say the speakers. Where do I find these CH numbers?

Radio, exch, 1 CD/MP3, AUXCH -60540 High Performance Sound System. Premium Sound System. EXCH FOR 30773442, 30775576, 31210147, 31215565, 31260544, 31285804 36050929

Radio, exch, 1 CD/MP3, AUX, IPOD/USB(US) CH 15272-175378 High Performance Sound. Premium Sound. EXCH FOR 31285531 EXCH FOR 31285837 With HD Radio. 36000993

Since my dashboard does not have the slot for the additional speaker I don't extend on replacing it. Also, not sure about getting the subwoofer either, but know i need the higher powered amplifier. Can't find a used one yet.
I'm sure I will have more questions so bare with me.
