I worked all weekend, Mon, today. I keep fiddling with the key in the glovebox and can't get the &#%^&&## thing open. I will get to the dealer Wed or Thu. Can't wait to see their reaction. They ask if they "get it right the first time"; this is my third try. I'm still toying with trying the Dension, since it seems the BMW iPod equals a CDC to the car, so I think my car's coded. Of course, add it up and we're over $1000. Luckily my credit card's on autopay, so I won't notice it.
Other option is to try to return the Dension; they said they'd take it back if I couldn't get it installed.
I still don't get why they couldn't have just made the same wire as 6FL and run it to the glovebox; obviously the connection to the radio HU is the same.
