I would recommend Archos 7.
Bright and high contrast 7" touch screen.
It's convenient to use in the car on the move, for the account of the big display and big virtual buttons.
Big HDD from 160 to 320 Gb.
All necessary communications: bluetooth, Wi-Fi, LAN, etc.
It's a pity is not present GPS receiver, but it's reparable for the account of use external bluetooth GPS receivers.
Btw, he playing .wav files (without quality loss).
