I recently purchased a 2010 G37x S.

My Google Nexus One phone bluetooth pairs with the onboard system just fine, but when I connect my phone via a USB cable, I get a 'check connected device' error on the car display. I did manage to get the onboard system to recognize the storage on my Nexus One once, but I havent been able to repeat it since.

Any ideas?

I think the problem is a timing issue due to the amount of time it takes the Nexus One to put the sd card into USB Storage mode.

The last post in the thread was someone else confirming that if he speeds up the process (by unmounting the card first) it works.
