Can anyone give recommendations for each of these on a 2014 S?

I have the amber display which has the HVAC settings built in, so I hear my only option is to get a new rear view mirror that will turn into a reverse view? I know that'll be tiny compared to if it was integrated into the dash, but I think that's my only option if I want it. I read in another thread that the wiring harness is different for the OEM Amber display vs. the OEM color display, and dealers were charging $10K+ if you wanted to do a dash upgrade.

And regarding the LED turn signal side view mirrors, can I get these installed at a dealership on a 2014 S? Is it even possible? Is the car pre-wires for it? Does anyone know the part number?

Edit: I found these 2 on eBay. I believe it should fit my S? It's non-heated, non-reverse downward tilt.

The price is WAY less than ordering through Nissan ($250 each) so it makes me wonder if it's legit...
