Wussup everyone, my friend referred me to this site since I just picked up a AVIC-N2. The unit I got did not have the antenna or map disc. I was looking on ebay and saw some aftermarket antennas going for about 18 bucks shipped. Is anyone using an aftermarket antenna with their unit? Does it work the same? Or should I just put out more money and get the Pioneer one? Also, does anyone have a current west map disc for this unit? Thanks in advance.
