what are the main differences between these units? i found a cd7100 for cheap and i currently have a cd7000. i have another car and i am wondering if i should stick the higher model in the better car and stick my cd7000 in my daily driver. will i be spoiled with stuff on the cd7100 thats not on the cd7000? also i hope that the connectors are universal? also id also like to not that i have been absent for awhile. but i am slowly going back to all the forums i was on.
