need a nav disc sticky thread made

can tideland or someone else make a sticky permanent thread that shows the different generations of toyota nav units and the correct discs that they need (the U numbers)?? thanks

I've run at least 5 different searches and can't find a thread that shows the correct U numbers for gen 4

I posted this in the audio electronics forum but haven't gotten a response from an administrator, thanks, the sticky will be a very helpful quick reference for someone shopping on ebay or craigslist trying to buy a DENSO disc and wants to buy the correct one.
