Hi to all. This is scpmore from Summerville, SC. Searching for installation ideas for the Clarion CX609 led me to your doorstep. While I am not the owner of a genuine Frontier, I do own a 2010 Suzuki Equator Extended Cab. It is a dead ringer for the Nissan Frontier - it should be, it was made by Nissan for the Suzuki folks. The interior is identical to your Frontier so any hints or help on the CX609 will be greatly appreciated. I look forward to reading all your threads and will respond to any that wish me to.
