Yes, that is the car company. (They're more than just a car company; they're a manufacturing conglomerate with quite a few product lines.) I'm used to finding strange stuff, but this time I think I outdid myself.
Hyundai announced 2 ereaders last week. The HYV-C700 and HYV-C600 have 7" and 6" LCD screens, which makes the C600 a rather odd beast. This is the first 6" LCD screen I've seen in a long while (if ever).
I'm having trouble finding complete specs, but from what I can tell the C700 has a 7" screen (800x480 resolution). It doesn't appear to have Wifi or a touchscreen. But it does have good audio and video support (720p HD, RMVB, AVI, MPEG4, FLV, WMV, MP3, APE, FLAC, OGG) as well as decent ebook support (TXT , PDF , HTML , ePub ,FB2,PDB).
There's no indication of price or availability, but Hyundai are planning to release several more ereaders, including at least one with a 5" screen.
