I wouldn't usually make an account just to thank someone this much but this works an absolute treat on my AVIC-F960DAB. Tested 01/07/18 and it still works! Saved me tons of time and money trying to get the previous owners details to ask them or pay Pioneer to come out and use a back door program themselves. Just make sure you're not a complete melon like me and remember to EXTRACT the files from the original zip file (even though it was made clear above). Thank you so much! Not all heroes wear capes...
