same head unit I put in my old zr-1 (now my sons) when I upgraded. I liked almost everything about it except how slow it was to switch music when connected to the ipod.
I chose to go with the viper keyless/alarm system on the car for a couple of reasons over simple keyless entry
1)remote start from my iphone, or droid
2)Regardless of whether anyone else would acknowledge the alarm going off it would page me through the key fob, or either one of my phones, regardless of distance, if anything was detected.
nice upgrades, you will love the keyless, and stereo/gps upgrades
