Which is better in terms of clearer, cleaner reception, a sat. ready head unit with a sat. tuner box or one of the self-contained units which is mounted in the vech. cab and uses the indash radio for fm transmission?
To add to that, definatly the FM ones will be worse then the other two. More then likely you will not hear a difference from the ones that are sat. radio ready and the ones that you run into your headunits aux. input.
i got the delphi plug n play xm and run it through the aux. inputs and it sounds great. the fm modulation doesn't sound terrible, but not as good as through the aux. inputs.
yeah on my sirius i have it hooked up to the AI-NET adapter on my alpine unit. and it works nicely. i love it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
