I went with the Honda unit as I cannot stand aftermarket stuff, I have never been happy with any aftermarket electronic device (stereos have too small buttons for my chubby fingers), they always worked as advertised, I just don't like them. The Honda unit works great, I use it when I am in the house and will be leaving in 10 minutes or so to warm up the car. Admittedly, it is annoying that I can't leave the car running and get in, turn the key and go, like the GM factory units, but I can deal with that, I just won't be using it as much. The range is good for me, I was three stories up in a building, and the car was across the street and it fired right up...
