Best/cheapest steeringwheel remote interface (for JVC)

So, does anyone have experience?

I recently visited the USA, but totally forgot to walk into a car-parts store...
(Still need these Camry connectors for the trailer hitch, a steeringwheel remote (e.g. (1) or (2) ) and a 2din frame if I cannot reuse an old plastic cabinet of a speaker that might just be the right size to fill the gaps on either side of the 2din unit)

I did get a credit card for the USA trip, so I can finally actually order stuff now

I'm asking because the parts are hardly available here, and if they are , they are insanely expensive (e.g. steeringwheel remote would be official JVC and cost about the same as my secondhand 2DIN 7" bluetooth headunit )

 

Thanks. The original post is 5 years old, but since I never throw anything out, I am still using the same car and headunit So still relevant!
