Persipity

Thanks for the helpful info, Lancecasper. This group is awesome! I've gotten as far as I have mostly by poking through threads on this. I tried contacting a couple MSCs about doing the work but none has gotten back to me. I have a Garmin dealer who's confident he can do it and he's located two -20s, but he's rightly concerned that a signoff from Mooney might be required. He'd also love the parts list for Option 2 in Service Bulletin M20-305B. Anyone have any (further!) hints? Does an MSC (still) need to do it? Finally, en route VNAV (Option 3 in the service bulletin) would be nice if possible (I have a GFC 700). Can someone tell me what (additional) hardware is required for that?

I'm yet another owner trying very late to upgrade my 2007 Acclaim to WAAS. I'm hoping someone can tell me definitively which 63W part numbers will work. I'm aware that I better get two of the same rather than mix 'n match. I see from MatthiasArnold's post that -00:no, -01:yes. Jayson: did you complete your upgrade with the -20s? Anyone know about -40s? Thanks.
