I'm looking to connect my ipod to the oem radio. I thought about getting the USA-Spec and also the NEO one as well, but found the iSimple version to be available at a local BestBuy and thought of picking it up. Only problem is the isimple site and bestbuy indicates the product only works for 06+ s2000s. I didn't know there was a difference between 05 and 06 oem radios?

Can someone clarify if the isimple will work with an 05 radio and also if there are any differences between 05 and 06 oem radio.
