Just purchased a new '07 EX sedan, no nav. I want to install XM using my MP3/Aux jack located under the power outlet on the lower dash.
I have looked at Delphi SkiFi3. It looks like I can install the roof magnetic antenna, plug into a power outlet, plug from line out on XM reciever to the Aux input on car. I could then use the XM/Aux button on the stock stereo to hear the XM.
Does this sound correct, or am I missing something?

We have been downsizing the last 2 years - an odyssey to an accord, and now a pilot to a civic - Thanks Exxon! The just posted a PROFIT of 9.3 Billion dollars for 3 months!

 

I use XM satellite radio just like you said. Magnet antenna on the roof, that i routed through the trunk, and along back windshield, and put it right in the center about 6inches from the window. Connect the power to the power outlet under the dash or in the center console. Connect the audio output to the AUX input under the dash of my civic and it works great. Just make sure to set the ouput level on the XM radio so that it is about even with your CD player audio. First time I switched over and nearly blew out my ears cause I had my satellite radio output set so low.
