First , does somebody know how to remove the stock radio from the RX8?
Second , what is the best I-pod adapter that I can connect to my stock redio?

Thank you

I run my Ipod through the AUX in my Sirius Sportster 4 has, crude but it works.

Mazda makes an adapter for the RX8 now. Search for OEM IPOD adapter.
If you don't already own the ipod you can look at Phat box

Thx A Lot.

Hope it works out for you
