Well, I agree that dealers tend to promote the products they sell for profit as being the best (and the potential for bias)... but I am having a hard time finding objective information. I could not find a good review of this Z130BT, or information that really points out how the Pioneer/Sony/Kenwood products compare to the Alpine unit. It does appear that the Acura units are well liked in terms of navigation, but I can not find information as to how they compare to aftermarket products. I would find this information useful because if I can have the option of a double-DIN opening in the dash without having to purchase the infotainment package, I would certainly go to the trouble of getting aftermarket instead if in the end, I end up with a better system for the same amount of $.
