I made the Forscan modification per the Expy spreadsheet that is supposed to adjust the stereo extended play timeout, but my stereo still cuts off at the 10-minute mark. Mine is a 2018 Plat Max, but I'm hoping someone who has gotten this to work on anything can help me find out why my change did not work. The spreadsheet says: "Stereo Extended Play (Drive-In Movie Mode) APIM 7D0-01-01 : xx?x xxxx xxxx Change ? To: A-Off, 2-20 minutes, 3-30 minutes, 4-40 minutes, 5-50 minutes, 6-60 minutes." I made the change in Forscan, changing the "?" position to a "6"; originally it was a "2". But the timeout was and still is at 10 minutes. Any ideas out there?
