Just went out to the parking lot here at work to try this. And yes, you can still remote start after opening all the windows by the key fob unlock button thing. I assume probably everyone knows this already, but I hadn't seen this answered yet on this thread...Thanks for starting this thread. I don't know if another thread like this exists on this forum, but I have seen one on Murano forum and learned quite many tricks/features from other owners.
So this could be another tip, can you remotely start the car after opening all those windows? The idea is to let the hot air from AC cycle through as you walk towards the car in the parking lot.
