Thanks for the welcome!
Honestly I wasn't considering any further upgrades. I really don't have an ear that discerns sounds all that much

, so the audio system with the car as it is now works just fine for me. I just really wanted to work the pod with it.
Thanks again!
**edit: The only thing that I will add is that when I was considering a new radio with aux input - i was concerned with how polished the finished product would look in my dash - especially given how the unit now is "encased" completely - if that makes sense...so it looks like those were my only concerns.
