For those that elected to use a DIN-1 radio (in-dash car type) instead of the Jensen and had ETI do an undercabinet mount, did their install fee include an enclosure?
I've used the same one I've found on this forum in my Casita:
POLY PLANAR Radio Mount, Universal | West Marine
I have one ready to ship if they need it, but can return it if they don't. Shipping to ETI cost more than the part!
