I have a 2001 C5 Convertible without a CD changer.
I have not seen a way to hook up an Ipod and a portable Satellite unit (Roady, Starmate, or similar) to the Bose head unit due to the existence of only one aux input. If there's a way to do this, I'm all ears.

I'm not willing to use FM modulation for either the Ipod or sat unit.
So as a compromise, I'm looking at other portable options to have satellite radio and mp3 capability. Here's what I've found so far:
1) Clarion NICE P200 portable GPS. It has a 20 Gb hard drive with 10 Gb for the nav maps and 10 Gb for mp3 storage. You can add a sirius satellite tuner that plugs directly into this unit.
2) Garmin StreetPilot 2730 GPS. Similar to Clarion unit but it has built-in XM capability and mp3 storage (but it does not say how much space is available for mp3 storage).
3) Pioneer Inno. Its a portable XM unit that has 50 hours of mp3 storage.
I'd love feedback on these options or any options that might be available.
Also, I'm assuming that the mp3s I created using iTunes will play just fine on the mp3 players listed above. Am I correct or is the iTunes mp3 format propriety to Ipods only?
Thanks.
