    I've just added the support of GPSMAP 66. It's available via the patcher's autoupdate.

    New version 3.80 is available: [Only registered and activated users can see links. ]
    This release adds the support of D2 Delta devices (I'm quite sure nobody needs this anyway) and includes all the recent patcher definitions - i.e. patterns for GPSMAP 66 and Edge Explore 4.00, 4.10, and recognition of Edge 1030 Bontrager, Astro 900, Rino 7xx GMRS and several localized models.

    Hi Alex,

    Thanks for maintaining it. Recently, the firmware for GPSMAP 62/78 devices has updated to 7.20. This version is not mentioned in the table on your site. Could you clarify the status (GPSMAP 62S)?

    Swall,

    My scripts checking for the updates on Garmin servers didn't show 7.20 last time I've run them - 7.10 was the most recent version.
    It's only now 7.20 appeared. The firmware seems to be patched just fine, but I couldn't test it in my GPSMAP 62s yet.

    That's OK. Every device owner (including me) can check if it's actually working. But only the author can make sure it's working as designed. So you're saying that you've looked into the new binary and have found nothing that prevents the current patcher from processing this firmware properly, correct?

    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
