I bought this camera back in March and used until April. I switched out my MS to a MX and it doesn't work on the MX. It's a very nice camera and takes about 5 minutes to install since it plugs into factory wiring. It looks factory once installed without wires hanging all over. Here is the amazon link where I bought it https://www.amazon.com/gp/product/B01MZZU9XM/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1 I was thinking $180 would be fair but let me know what you can offer.
