Howdy, I am a new member here and an owner of a 1975 M20F since 1991 (has it really been 21 years?!). I am in the middle of a major avionics upgrade and I am evaluating everything in the panel to decide whether to keep, update or remove. I noticed Insight is offering an upgrade path for existing owners ($1k core applied to a new unit). The replacement cost is still steep (I think street prices would still be over $2k). \
Anyways, I was wondering if anyone has done this upgrade and if so, do you feel the investment was worth it? Could you also tell me what you upgraded to? I have (I think) the original 601 (no digital numbers, just bars).
BTW -- here is what my poor baby looks like as of late last week...
