Was it for the 4/17 trip? They said they send instructions via email. Was told I'd be apart of that trip but haven't received anything and emailed them last week.
There's definitely plenty of other great roads, I did about 3 hrs worth the same day. Luckily I got to the dragon about 830am during the week and only saw 3 other vehicles going the opposite direction, so really got to let it rip. Other roads were more scenic with longer flowing curves but none...
Got it after removing and reconnecting adapter, using same one btw. Have you had issues with it and bimmerlink dropping sensor values? Connection to adapter is always good but after 5min in bimmerlink it stops reading sensor values.
