I really can't decide how i want to install sirius in my car. it would be nice to hook it up directly to my radio thru my 6d changer but i've been looking around and it seems like that's more expensive then just buying a dash unit.(like several hundred for unit and install) am i correct on this? because if that's the case i was thinking of getting a stiletto, that way i can take it in and out of the car. do you think one of those would fit in the little holder that flips up from the middle console? i usually put my phone there, but i think if the stiletto fit there that would be rockin. any feedback from people who already have sirius installed??
