We're supposed to keep the same truck but at Chicago whenever anybodys truck is in the shop or been swiped then they tell you to go find another one. Its pretty much a free for all mess sometimes. This one has a Panasonic with a CD player. No Aux jack but it does say "Sat Radio Ready" on the front of it. Instruction book is long gone.
I kept that FM modulator hooked up and leave it in my truck since it goes behind the dash, then just put in the magnet mount antenna and radio in when I get into work.
That FM modulator works fantastic (see earlier link) because you unplug the antenna from the back of the radio and it goes into that box, then it goes to the radio. I stay on one channel all day, even driving through big cities like St. Louis or Dallas.
