Hey all, sorry for not replyign to your posts! I thought I subscribed to this. . .but I did without email notification :P
In terms of the maps. I do have all my maps on my hard drive, but I keep them on my 1 GB SD card. Mapopolis searches through every map every time I load up, so for the sake of load time, I keep them on my SD card. If ever I need to get other maps. . . I can pull on the side of the road, and just transfer them over to my SD card.
The wire is such only for power. It's actually not connected to the hard drive. I need to do a more updated video now that I have more stuff . . .. but I"ll probably make one when I finalize EVERYTHING and get out most of the kinks.
But anyway, the hard drive has wifi built into it, and that's how I connect. The cable you probably see is from the headphone jack into the auxiliary input in my car.
Thanks everyone for your compliments

But I have to say. . . I"m starting to not like playing videos while I drive. . . it can be quite dangerous. . . and I'd hate to feel like an idiot to actually get an accident because I was laughing at a funny part on Anchor man and wasn't paying attention. . . :P
