Clarion CZ209 - Car Stereo In-Dash Receiver at Sonic Electronix - Sonic Electronix
Pioneer DEH-2200UB (deh2200ub) - Car Stereo In-Dash Receiver at Sonic Electronix - Sonic Electronix
never had clarion like usb location, dont know about EQ; pioneer love the eq not so much usb location;
both: dont know about ipod interface
i haven't really ever messed around with a clarion headunit, but i like the fact that the usb connection is in the back and hidden. i have an ipod i'd like to just throw in the glovebox and leave it there. i have never used a clarion EQ. which brings me to the Pioneer. i have had an older pioneer and loved how you can turn the back speakers for lows and how you can select the frequency the eq adjusts. however the usb plug is in the front which i don't like too much. how are the ipod controls/menus on these units. i'm not expecting too much w/o a screen but i still would like an easy navigation.
