Well, i have finished the camry navigation system for the most part. Everything is good to go. I just got the XM unit in today. My camry nav has the option of adding a XM module to it. I bought the XM module that was meant for a ES330. It came with the brackets, harness, HUGE antenna, and module. The cheapest I found it was 410 dollars. Toyota wanted 650 for the Xm module for the solora which is the same thing! I will install it when i get some time and post results.
