A:Answer I bought mine at the store. They put all the parts for installation in the bag when I paid for the installation, which had to be scheduled on a different day. There are a few parts: a radio kit ($20), harness($20), antenna adapter($13), plus $65 labor on the bill and the cost of the radio. I came out to about $225. I checked with a local installer by recommendation first and was told that Accords don't have kits. So, go to Best Buy, they know what they are doing. I at least am glad to know my car won't look ridiculous.
