I noticed I misnamed the zip file Since I cannot edit the post I cannot rename the file. But the zip does contains the 4.70 update file.

Like the one in Montana, so I will never buy it, otherwise I will have to buy back all the Garmin Topos maps that I have already paid for. It's too expensive. I keep the 66sr which has the same functions in fact, nothing more for me, for hiking.

The firmware is supposed to be encrypted for 67 same as Montana 7x0 and Alpha 200i. So JNX patcher will never work.

This is the advantage of old Garmins, patching them to be able to use maps of my manufacture, so I keep the 66sr.
Garmin now restricts these GPS while Twonav allows without patch to read all the personal cards from where they come provided they have their RMAP format, there are softwares which allow to transform the cards into several formats and Mobac knows how to do that directly.
Future Garmin GPS will all be restricted.
People are complaining and won't buy any more because they have to buy back all the Garmin maps that are not adaptable to another model of Garmin GPS, it's obvious theft.

Back on topic: Garmin has posted the release notes of 4.70 on the Garmin Forums:

• Fixed issue with selecting position format in some languages
• Fixed potential “Can’t Authenticate Maps” prompt
• Fixed potential issue getting stuck or crashing while loading maps
