i have the 1809 in mine and i love it.
the fascination is that for a very low price, you can get a 160 watt headunit that looks factory, sounds great, and does much more than the factory one. I use my ipod a lot and can tuck it away and out of sight and change songs from the radio and steering wheel, and i get the title and artist displayed on the unit.
i also added a custom background to it with a 9 second clip of a nice motoGP battle. lol.
for the $148 i spent, i have no complaints.
