if you want old-school looks with bluetooth, Minuit is adding AUX ports to the old radios and then you just need to add a bluetooth dongle to it and BAM you've got it all. I'm rockin' a '92 XJ unit in my '06 Liberty.
note the charging cable for my phone. since I needed to add in a USB charger in the dash for the dongle I choose, I got a double-outlet and now I can charge while I rock out.
