These part numbers are ones that are a mix of ones customers have used previously or ones we believe should work properly however have not tested and are NOT WARRANTY COMPLIANT nor do we guarantee perfect OEM operation with. Again we *think* they should be fine but the best practices list exists for a reason as does our kit containing all the proper hardware. If you are looking to do a Denali Cluster upgrade eventually or other upgrades we again HIGHLY recommend using the best practices list or simply having us supply the proper hardware in our kit; we sell the parts at dealer cost.

That being said any part number under the heading you are looking for so feel free to search for all of them if need be. Reminder: You MUST match your audio type to your radio module e.g. Bose equipped vehicles need a Bose radio you cannot mix them up.
