I wouldn't sell the aftermarket units short. IMHO, they would be as good if not better. I have the factory Navi, just traded in a 2005 Jeep GC with a factory Alpine Navigation unit as well, and neither one of them is really as good as my Dell Axim X50v with Garmin G10 Bluetooth unit. The data base is much better and the voice commands are also better. I think overall Garmin makes the best systems from what I have seen. You can get dedicated units for $500-$750, but they are not the entire entertainment system type units with CD, radio, etc. For about $1500, though you should be able to get a kick butt Pioneer system. Lastly, you are crazy if you still buy electronics from local brick an mortar stores. I have probably saved $4000 last year alone buying stuff from reputable on-line dealers. Buy it on-line and install it yourself. If you don't know how, ask someone on-line or get a friend to help. There are several Honda aftermarket parts that give you the detailed dash removal step necessary to install the entire system. Here is a link to some units from Etronics http://www.etronics.com/listproducts...pc=&prod_type=
I am not sure how good they are, but I know some of them have back up camera options, Bluetooth, etc. Somebody here posted about a Pioneer unit a few days ago.
