That is about right for the EU firmware with the biggest wait being the camera. The aircraft will usually connect shortly after the aircraft initializes, and the camera takes longer with EU firmware due to finding a channel that is not being used by weather radar.
Booting up can happen well before one and a half minutes but it is the satellite acquisition that can take that long, or longer, depending on location and and other factors. Here in the US I would typically wait till I had 11 or more satellites locked before take off, and that would be about the amount of time I would wait.
I have loaded the US firmware few weeks ago (did not make myself very clear in my original post)
So my question should have been - with the US firmware loaded, what is the average boot up time for the H in the US
