Since I picked up an existing order, I inhereted a non-monsoon sol. If i had the chance, I would have changed to the monsoon, but no sense whining over spilled milk. I would love to have in-dash DVD, but I have obvious concerns about the security of that. I asked my dealer if adding the monsoon aftermarket was a possibility, and he shot that down saying the cost-benefit wouldn't be worth it. What are people doing to upgrade the sound system aftermarket?
