Well after a little more thought and research I am returning this stereo. Reason being that it's not compatable with iPhone 4 without software update and I don't think I can stream audio a do gps at same time. I plan on saving/ spending a little more on a newer double din that has pandora and streaming built in.

 

this is really nice

 

Sorry for bumping such an old thread but do you guys have to buy any extra extensions or wires ? Or is it just a plug and play?

I'm planning to get the nz503 and was wondering if I would need to purchase anything else besides the system itself.

Thank you!

 

this seems way easier than putting in a double din lol
