This patcher removes the regional checks that disable the radio functionality in Astro 320, 430, 900 and Alpha 100.
The testers report some functions do not work in their collars when the patched firmware is installed. Anyway, this is better than nothing.


Everything it pretty simple:
1. Download a firmware for your device - it would most likely be a file with GCD extension or an archive with a compressed GCD file. For example, the latest firmware file for Astro 320 is Astro320_460.gcd.


2. Start the patcher and open the GCD file in it, the patcher will make a new GCD file in with _Patched suffix in the same folder as the original file. In our example, the filename would be Astro320_460_Patched.gcd.


3. Make sure you have a fresh set of batteries in your device. Connect the device to your computer, copy the patched GCD file to the device's internal disk into Garmin folder, and rename to gupdate.gcd.


4. Next time you restart the device, it should install the firmware.


In case you already have the latest firmware installed in your device - in the example above, you have Astro 320 which runs the firmware 4.60 - to install the patched 4.60 you'll need to change its version first.
To do this enable "Adjust firmware version" checkbox in the patcher's window, change the value in the edit field to the right to 1, and then process the file.

After this, the patcher will change version 4.60 to 4.61, and the device will "think" it really makes a version upgrade.
