Some feedback about the two units shown in the thread
The mount setup shown does not work with the GS bars certainly on the Hexhead variant
The Ram type arm is OK but the U mount needs loads of washers to take up the short threading of the bar
The profile of the two bar clamps is not well suited to the GS bars,
and will need your bar wrapping with a good build up of electricians tape, to allow the clamps to lock to the bar
The unit is very similar to one i had some years age, which was a clone of a working android unit,
but was hardware locked so nothing could be updated.
I currently run an 8" tablet, which even when running co-pilot, can look cluttered.
The more you have onscreen at anytime the less maps you can see overall!
This looks like its just updated to a later android version,
However if you look closely at the advert for the Otto unit, its just wallpaper, as in its just words to entice you to buy
1) Spelling mistakes, look for the Momory setting?
2) 5.8G wifi module - yet the unit only shows 4G
3) IP7 rating - the unit is glued together sealed to prevent water ingress for 30 mins at 1' so no replacable battery
4) Wriless headphones, i guess this is another new technology they have invented
5) Bluetooth 5.0 but no profiles mentioned ?
6) Automotive specification chip - What chip & what specification?
7) Free demolition loading - wow, haven't a clue
8) Built in speaker (3W) , you can work that one out
And I guess the icing on the cake,
It uses CarPlay which as far as I could see a few minutes ago is not available on the android app store?? , hmm but that's ok,
as Siri will make a call for me to find out why , as she's a totally different OS, as is CarPlay
** update**
Just checked, Android auto, is a stand alone program that runs from your car's console / dash
It's supplied to automotive oem,s & audio oems
The car unit does all the work so to speak, with your phone or tablet talking to the master (car) unit
So if this unit has AA, where did they get if from ??
