i like the viper 5901 i have in my xb. good 2-way remote system. Got it installed at my local Best Buy (costa mesa,ca) and they did a perfect job on it. no hiccups.

gluck man! or you might have already gotten something in there hehe..

 

I have the Karr system. I haven't really heard anything good about Karr, but the dealership where I picked up my xb offered it to me free of charge. I figure its better than nothing.
