first question.  
Is this the latest firmware version  
com.zubax.gnss-2.2-4.1.62c8d4a.compound.bin 2017-11-21 20:05 209K

Second question. Does it make sense to upgrade.

Third question. Anyone have a link to the can interface tool. I understand you can’t upgrade the gnss wiht out the can port tool. So I guess I might need one.

Fourth is there a way to determine what version is already on the device.  
I get no sats so I want to make sure the device is up todate.

Yes.

Yes. It has new features, such as support for Galileo.

We have [Babel](http://zubax.com/babel), but any other adapter compatible either with SLCAN or SocketCAN will also work. The PC software is avaiable from [https://uavcan.org/GUI\_Tool/Overview](https://uavcan.org/GUI_Tool/Overview).

Connect via USB and run [`zubax_id`](https://kb.zubax.com/pages/viewpage.action?pageId=2195516).
