I did a Sync 3 retrofit on my dad’s 2013 F150. It has an APIM from a 2018 F150 and for the most part it has worked well (since we swapped out the counterfeit APIM for a salvage yard unit). It does have 1 very annoying issue, when starting the truck after it has set for a while (like overnight) sometimes the volume is set to a high level. It seems to set itself to 14 most of the time but today when we got in it, it had cranked itself up to 18. Is there a way to set a maximum startup volume? This issue never occurred before the Sync 3 retrofit so I’m assuming it is related.
