I bought this Cassette Module to replace the degraded unit in my 2003 GMC Sierra, It came via UPS and was very satisfied with the shipping time. I was in the process of installing it when I discovered that the one I had ordered was the same part number, but I needed a different revision of that part. After contacting them for assistance, Kevin reached out and informed me that the control boards have different plugs for the stereo but the control boards between the parts can be swapped. This was true as I swapped the boards and now it works beautifully and I can now listen to my cassette collection while commuting. Thank you for knowledgeable staff, quick response and great products.
