Frank, Don't worry about the learned codes. Though the numbers look different they still serve the same as a "created" code. MakeHex creates a clean code that should be 100% accurate. A learned command will work but every now and then may not. However, if you go to pioneercustom.com you will find the US models listed. There are Pronto ccf files that can be opened with ProntoEdit4 and give you access to the hex format that MakeHex creates. Almost all (I may have missed one or two) are MakeHex created commands. So I've already done the work for you. In the near future I'll post files that will save a step as they will list the Pronto hex in a spreadsheet-style pdf. Good luck!
