Hi ....... New member here. 5 days ago I purchased a 2021 Honda Passport EX-L Deep Scarlett Pearl color. After the purchase I realized the car did NOT include the Rear Parking Assist feature and now I would like to check out having it installed by a Honda dealer. Has anyone else had this done to their Passports and if so what costs are involved and how long did it take. Any other info you might have would also be appreciated. Thanks
