Wow, just would ot work on one of my chars. Untill I saw this and returned my car so I had no PV on the map. After that it worked first try, lol Thanks MystikMunk420We failed 5 times before we figured out the little tips to make it work first try.
Make sure you do not have a personal vehicle on the map anywhere. Make sure you tap triangle once then tap and hold as your getting in friends avenger. Once in spam right dpad and you should get the alert (top left) to modify the avenger...tap and twice to enter armor and change it once quickly before you get kicked from the avenger. If you get that far...exit all from facility, call our your (new) avenger and confirm its the new one. If it is, send it back. Swap characters to save it (not sure if that's necessary but I did it)
