I'm contemplating two options:

1. Replace with a slide-in replacement like the TKM series, which will get
me a new box and standby freqs (woo-hoo!) Anybody here have those, or
suggest others? Advantage here is v. low cost to install versus something
like a KX-155 upgrade which would require rewiring, etc.

I replaced broken Narco COM121 (or is it 122?) junk with TKM MX11R.
Been happy with the choice so far (3 years). This was probably my
cheapest option involving new equipment. It's a slide-in replacement,
but in my case unlike yours it's com-only (no nav).
