I'm looking to get a double din headunit with an LCD touchscreen to replace my factory '03 non-Bose and came across the Panasonic. It doesn't seem that expensive at all, but the price brings up a few questions. Does anyone have any experience with this headunit? If so, what are the positives and negatives for it when using it with the Z? I don't want to spend $400 to get something that can't even power up the factory system, haha. Thanks for any help!
