Looks like the head unit size is exactly the same dimensions as the previous models (surprised as they shrunk the UHD9 series 2 model) Just like the UHD9 Series 2, this model now has wireless networking but unlike the UHD92 model, this one gets the screen recording feature! (previously only available on the GPSMap series) kinda nice!
The only drawback I see is that by adding wireless networking, it also increases the power usage upto 5 amps max! Previous model was 3 amps max…so it will be interesting to see what typical battery consumption looks like out on the ice…
