hi . got the invite for the camera upgrade, i first scheduled it for an open period this Wednesday at the Sterling VA SC ( those guys are great!) , they very quickly ( like in 5 minutes late in the evening!) said that they had to re-schedule it slightly later so the techs had time to get the parts and familiarize themselves with the fix ( to probably stay within the fix time frame, they get dinged if they take too long).. I'm scheduled for the 20th very early in the morning so lets hope to see if stays that date. I already have MCU2, and HDW 3 upgraded on the April build 2017 S 90D . im running a 98 safety score ( man it is hard to keep it there with the traffic in Northern VA!) . I'll see if I can talk them into pushing 10.4 to me while it is in. i'll let you know what happens. Finger's crossed!
