For those who don't have a built in DVD player, this is kind of cool: I know it's neat to have a built in DVD player in the Enclave, but I don't have that....however, I found out that I can hook up my portable DVD player to the car stereo speakers thru the AUX input on the dash stereo. Yes it's cords you see, but I think we will try this next time we have a little more of a drive, and see how our kids like it. We purposly didn't buy the built in DVD in the Enclave because we think our kids watch too much TV as it is. However, this will be a neat "treat" for them, once in a while.....and the fact the sound will come thru the car audio, will make it seem like it's built in. Kind of excited to try new things with our car, these new stereos are really cool, even the base unit.
