Just getting started on this. The CarPC originally destined for my MX-3 didn't quite get to the install stage and is now destined for my Z.
Although I have the mp3car Transflective TS, I'm leaning towards a double din unit install. By most accounts, the DWW-6500 seems to be the front runner in that department and I haven't been on here regularly to know if something else has surfaced that addresses the shortcomings of the 6500.
For now, I've acquired to JDM bezel faceplates from Japan and have installed a Double din CD/DVD/FM/TV/Aux tuner/amp using one of those trimplates which is aluminum covered in vinyl. It took a bit of work to get the correct alignment and it's onlt a temporary measure to see if I'm OK with a double din install.
I'm considering on selling my Transflective so as to purchase a DWW-6500 since I want the AM/FM capability that seems to be the ever so elusive goal in the CarPC world. I think the biggest downfall of that 6500 is the lack of pre-outs or audio out to the PC for processing.
At any rate, here's my trial double din unit pending my decision to stay with the transflective or go with the DWW-6500.
