Please use the "search this topic" at the top of every page with your device name DriveSmart 65 and you will find multiple posts saying it is NOT patchable.

Hello everyone!

I just bought a used Garmin Astro 320 and I have a new Topo map from a friend I could use but I need to unlock it first. Can anyone provide an update file?

The device has an old software on it, could it be possible to have the latest v4.6 or at least something newer?

This device does not need to be Patched to use Unlocked maps.
Use Garmin Express to update your FW
Astro 320 | 1339 | 460 | MAP: Yes | GMA: Yes | MSV: ------ | GVS: --- | File: Astro320_460.gcd
Legend:
Show Spoiler
MAP: Yes - it verifies the presence of a valid unlock code, to unlock an .img you can simply use JetMouse keygen.
GMA: Yes - it verifies the FID limit (2200) and the presence of a valid *.gma, to unlock an .img you enough to use the old gimgunlock-0.03 (without MapSigPatch) or one of its derivative.
MSV: Weak - it verifies the validity of map signatures in a simple way, you can unlock an .img using gimgunlock-0.04 (without patching your firmware), but in case of unicode maps (CP65001) you must modify the CP value (see the Temporary authentication of Unicode maps*).
MSV: Strong - it verifies the validity of map signatures more complicated way, in this case you need to patch your firmware and unlock an .img using any correct unlocker.
GVS: Yes - it verifies the validity of firmware signatures, you have to use Updater.exe to install the patched firmware for the first time.

Use at your own risk I do not have this APAC device to test, but it was treated the same as the non APAC version.
