Just got the handheld Delphi Myphi. Mounted the antenna up near the light sensor on the dash, plummed it into my RCA box and was rocking. Sound is great and the best part is I can take it wherever I go with the built in antenna it has.For those of you who did not get the XM option,They list for like $350, but I found mine on a CA site, craigslist.com (http://www.craigslist.com)for $200 from a private seller. I highly recomend this. :D
