Bass, what was poor about the 501. I've always heard good things about clarion.
What I mean is when compared to Pioneer, Alpine, and Kenwood the Clarion is just not for me. I also have a Clarion dxz585usb and I think the ipod control ***** compared to Alpine. I've heard good things about Clarion too, but I'm harder to impress than most. It is easy too see if you use different brands. I've done direct a swap with a Clarion 6 volt unit to a Pioneer 2 volt unit and the Pioneer sounded louder even with gain turned down. Maybe Clarion is improving but I must go with what I know works for me. Not being able to go back a step on the ipod is a deal breaker for me.
Nx501 Con List
-Kind of hard to see in Sunlight and I have 35% tint up front/ 5% in back
-Remote doesn't see the unit worth a dayum.
-When you use the volume knob, when increasing volume it will decrease the volume as you turn it up. This happens all the time. For example it you turn it all the way down, it sometimes will jump back to "volume 1"
-Does not pick up ipod no matter what cable you use. It might pick it up 15% of the time. You have to keep reaching in the glove box to unplug it and plug it back in for it to pick up.
-You cannot go back a step on the ipod. You can go back but you will be right back at the letter "A". It gets very annoying to go through all that just to get back where you left off.
-Touchscreen could be a little more sensitive, but not too bad
-Volume knob is right under navi button so when you turn up the volume, you will keep touching the navi button. Keep in mind navi button is not a real button. All you have to do is barely touch it, and navi screen pops up.
-Bluetooth audio has low volume compared to Alpine and Pioneer.
-3d mapping takes a long time to render buildings.
-Hard bass can make dvd skip. Sometimes when it skips it starts dvd at beginning.
-You cannot hear the navi voice without some kind of music playing in the background or it will just be muted and you have to watch the screen. Sometimes I like to hear the navi without music playing at the same time, but this is not possible with the 501.
-No sub on/off option, but I knew this before I bought it.
