Back up cam slooow.

Why does it take so long for the back up cam to come on after initial engine start up? It used to be quick. Anyone else?

I agree with your complaint.

1. For starters, it takes far too long for the COMAND system to boot up. I suppose that's an "operating system" issue.

2. In any case, after the car is put in reverse, there is an unacceptable delay in getting a backup cam image. And my car has never had a quick enough image.

Was it ok in the beginning?

I used to have this problem. I reverse out my driveway every time I leave. It used to come on just as I entered the street. That was not particularly useful for me.

But earlier this year I got a software update for unrelated reasons. Now, I start the car, put my seatbelt on (backwards, I know), put the car in reverse, and the camera is ready. Now I can't even get out of my garage before it comes on. That's perfect.

The tradeoff is now my phone takes longer to get ready, maybe 30 seconds or so? I can live with it.

Maybe the software boots up the backup cam first now and the phone last? Seems logical.

I find my back up cam pretty fast . As soon as I shift in R ,I see rear view on my Comand screen and it goes off when I shift out of R

As for the phone's bluetooth audio connection , yup it takes a while unlike reverse cam it's verily slow to get it connected .
My phone is Nokia N8 lol

Backup camera loads very quickly if the car was already on, say if you're parking. When turning the car on and backing up for the first time, it does take a bit longer because of the COMAND start up screen.

Really really wish it had backup sensors though, I find those much more useful in my A4 than I do the backup camera.

But mine just started being sluggish 2 daysfire ago after a year of reversing out of my garage onto sidewalk. I now have to back in so i can pull right out. I guess i should take it in.

Did you do anything different to COMAND two days ago? Install a new player? Take out a player? Start listening to CDs rather than radio? Change any settings?

For instance, the CD player looks up song tracks and album titles on Gracenotes, and does so at startup if you are currently listening to CDs. If you put in a new CD or just started listening to CDs, Gracenotes might be interfering with the bootup of the backup camera. Before my software upgrade, Gracenotes almost never found the tracks or album titles for my CDs, or would do so very randomly. Now that both Gracenotes and the camera are fixed...
