I'm pretty sure PCM updates are just Map updates for the GPS system. If your 2001 has a PCM 1 unit, it uses CDs for the map data. So... do you want to buy some antiquated Navigation CDs for over $200? You can get a nice mount for a smart phone for under $20 and use that for nav and have current maps.
