[C320-list] ST60 Replacing ST50 Instruments?

[Scott Thompson]

We were able to reuse the existing in-mast wiring for the masthead unit 
when we did an upgrade a few years ago. Can't answer the other questions 
since we converted to the newer version of SeaTalk and replaced all 
other wiring at the same time.

A friend with a 2000 Cat320 has just upgraded all of his instruments to i50/i60 along with a new chartplotter, and gave me his ST60 instruments and transducers (still working fine).  Replacing my existing instruments and transducers with these will effectively update my system by 6 years.
