Sorry, it took a bit longer for me to respond.
The current Navio2 image we provide isn’t outdated. At this point, it’s based on the older version of Raspberry Pi OS, but it’s still maintained. The latest release introduces something new, for sure. But since Navio2 uses ArduPilot firmware which works on a command-line interface, those changes might not be that useful.
There should be no issues with the installation process on Navio2. At this moment, we don’t have similar reports from other users. But if you encountered any, please tell me more about it. I’m sure we’ll figure out what exactly caused it.
It’s not on our agenda now, but we’re still providing technical support and any other help concerning Navio devices.
Navio2 is still can be purchased in the store with other Reach devices. We didn’t create a separate store for the device. The new Navio2 page is for all future users that want to know what the device can do. You can use the link to the docs from there or use popular search engines, for example.
Thanks for drawing my attention to it. We’re currently checking the question about the pricing in the Australian store with our dealer. The information should be updated at the nearest time.
