I have had a new C7 for about 5 months and love it (of course). I had one problem that was fixed by Chev., but I wanted to ask you all for your opinion: The middle screen which shows the speedometer started blacking out. After a couple of times, Chev sent away for a new one and it hasn't occurred again. Even though there is no real logic to this question, does anyone think that this might in any way have been caused by me hooked up to the USB, my Apple IPOD and playing it? Once again, no real reason to think it, but wanted your thoughts. Possible power surge or something? By the way, tried connected IPOD by Bluetooth, but it didn't work.
