Re: Battery level indicator

That’s only possible for a device with an internal, or smart battery pack. If the batteries in a Garmin are sitting right at the nominal 3 Volts between them, how is it supposed to know if it has dirty old carbon batteries from the 80’s with ten minutes left in them? You tell the Garmin the type of ...

Re: Idea: File-Transfer App

Easy in theory. I’ve done five Apps for Apple’s App Store,
and can almost guarantee nobody will ever write an App that links an iPhone or iPad directly to a Garmin GPS.
File exchange over email maybe (I’ve done that), but not over USB.

Re: Anyone with a GPSMAP 66i? (Need Screen Captures)

There’s a Facebook group where you could ask, or I could for you. Several owners there.

66st Whiz V6

Hi,
I was reminded of this last night, and may be of interest to someone.
Will of course void your warranty if Garmin knew about it. Tested on Camera.
Links are in the video description.

Re: GPSMAP 66 GPS Software 2.70

Also, Garmin are lying.
They could increment the version of an older file much more cleanly than I can,
and also push it through their usual update system as a roll back.
It wouldn’t be the first time it’s happened in the software world.

Re: GPSMAP 66 GPS Software 2.70

It’s 2.60 downloaded from the files section here. The version info strings displayed in the about screen are meaningless, and could be changed to say anything of the same size. The actual version number 0x0104 (decimal 260) reversed for correct endianness (0x0401) appears in the gcd file before the ...

Re: GPSMAP 66 GPS Software 2.70

Nope. That’s actually a later version if it were possible (which it isn’t).

It’s 270, and 260. There is no decimal point.

Use at your own risk, and don’t power the unit off while updating, but immediately after.

Re: GPSMAP 66 GPS Software 2.70

They call it MT3333 in the GPS firmware version 2.60 and in 2.70. Is there a way to upload a file here or something? I’ve created a 2.60 GPS chipset file that identifies itself as version 2.71 inside the gcd file wrapper, and recalculated the outside gcd checksum, then copied it to the device Garmin...

Re: GPSMAP 66 GPS Software 2.70

Garmin should provide a rollback version if they supplied a dud.
It’s a MediaTek MT3333 GPS chipset by the way.
