Yes... I am one of the FEW people who got On* to activate the VCIM and had everything working 99% properly BUT On* always saw a 2009 Acadia, where the VCIM came from! They did manually enter my VIN and "add" my 2007 Silverado to my vehicle list, but I was always seen as owning two (2) GMs. I have NEVER been to a GM dealer or have ANYONE besides On* do any programming.... they did all programming remote. When my free period with On* ended, my LED went from green to out, no colour displayed, not RED like most VCIM swaps.
Now, after calling in and putting my name in the draw, they have re-activated my On* account (new account #, new phone # that works) and I have free On* for 6 mos! The topper, when I did this VCIM swap and they couldn't get their system to recognize I was in a '07 Silv, they gave me like 100 something minutes free phone... I still have 128 left and it works! Had the wife call my new number and I can receive calls, but DIC shows UNAVAILABLE since there is no call display.
Now, I have a GREEN LED once again, but On* still sees a 2009 Acadia.....
EDIT: BTW: for some reason, I have all my minutes back as well. Back to 130 minutes phone with On* as opposed to less than 100 last July (an older post I made here in another thread kept record)
