Kit is well-designed & despite not having built anything since getting my ticket, I was up and running within a day of it hitting the mat.
I'm using Xastir (and the maps are now working with the latest version of Raspbian).
I first configured a serial connection, but now use i2ckiss to connect, & have an Ultimate GPS (Adafruit) on the uart.
Still thinking how to get a decent cheap portable(12v) screen....
Oh, and a case better than a ready meal container & lid
