I got this backup camera for my '13 Mazda3 with Sat-Nav. I ran across this find on another Mazda forum. Ebay seller who is affiliated with a Toyota dealer in CA said it works on all '13 Mazda with the big Sat-Nav screen. Got it in 3 days. Here is a pic of it. It looks pretty much "plug-and-play." Will have to wait for better weather (rain almost everyday here) to do the install. Keeping my fingers crossed. Will update with working pics.
