I'm looking for installation schematics for the TKM MX 300 Nav/Comm.
I see lots of vendors for this radio, but can't seem to find the TKM
website.
Thanks in advance

FWIW, the TKM owner's manual that says "for new installations, use the
installation instructions for the RT328T". It is an exact replacement.

They do not have an independent web site, but you can call them at 480
991-5351. They are now colocated with US Avionics,
