I am looking to install Navigation in my new truck and was curious if anyone had any model recommendations. I really like the Pioneer AVIC-D3, but it isnt as available as many others are. So before I pay out the nose for that one, are there any other really good ones for under a grand? I am looking for one that has these features: Navigation iPod connectivity DVD playback MP3 CD Playback Touch Screen capability ID3 tagging Thanks in advance!
