This is great!

I just bought an '07 Solara SLE convertible - Pearl white - and I love her!

I'm anxious to find out how to get the satellite radio working. I'm told it's "Satellite ready", but I need to spend some money for a receiver & antenna. This is my 3rd convertible, but my first Toyota.
Houston allows me to keep the top down most of the time, so the top won't be seen unless it's raining or really cold.
Any hints or ideas for a new Toyota owner would be greatly appreciated.
Thanks in advance!
Judy
