81X Posted June 10, 2022 Report Posted June 10, 2022 After taking to a few shops, it would appear that the WX500 takes a field approval for a proper install. Has anyone been through this process at all and can help shed some light on it? Bonus points for any 337 or approval letter paperwork that may help with this. Quote
