Part 43 requires an A&P to at a minimum sign off the installation,
maybe do a 337. I believe there is no actual requirement to have a TSO
radio. However your A&P/avionics shop may disagree. They may require
the radio be TSO'ed to feel comfortable about complying with the
language in part 43.13 and maybe elsewhere. If you disagree with their
position you should ask that person to explain why they believe what
the radio must be TSO'ed. You likely are getting many options
expressed because different people interpret part 43 requirements in
different ways, and in some cases may be dealing with local FSDO
preferences for 337 paperwork which might further encourage caution on
the part of the A&P. I would find a competent A&P you trust and follow
the requirements/procedures they recommended.

The shop where I work just installed an non TSO radio in a glider. I
asked the avionics "guru" (my boss) about it. He said there is no
problem at all. Just paperwork issues. He has a great rapport with
the FSDO so never any paperwork problems. Basically the installation
requires a 337 and "field approval". He said somthing about providing
"approved data" which can be as simple as the install manual.
