What i am about to say is not an attempt to flame you, but maybe just making suggestions.
First of all, the dual unit u had was and probably still is crap and i mean pure crap. Secondly, I think you may have made a mistake in buying a walmart one to replace it. Instead, i think you could've saved up about 100 more and get a better unit on the net, or from the classifieds in various forums.
I'm pretty sure that ur HU rite now will more than likely end up being like your dual unit, i hope it doesn't, but more than likely it will. And if it doesn't, it probably won't offer you all the features that other slightly more expensive units can offer. Really i think by buying this unit u will just be disappointed with it later, like i was with my Aiwa
But anywayz, sorry for the long post, just trying to give suggestions. Have fun with it though
Edit: I guess pioneer is not so bad, but u should refrain from buying anything but raw materials from walmart
