Not quite correct.
The patcher itself is the best tool to check if a firmware can be correctly processed.
Its search patterns intentionally include a lot of redundant bytes just to prevent false positives.
So, if a firmware is patched it should work, and if it's not patched, new pattern should be added

Thanks for the clarification about the design's maturity. Anyway, who knows what Garmin is going to do. Each version comes with the risk of protection hardening. I've installed the 7.20 and it seems there are no complications, fortunately. The characteristics are kept (MAP: Yes | GMA: Yes | MSV: ---). As for Garmin signature verification (GSV), your patcher is an excellent tool to verify that there are no improvements in that regard as well (hopefully). So I'm going to try it soon and report the results here
