With regards to the unit or units of that ilk,
In short, don’t bother, its a £10 nav in a £1 case –
It will have a cloned front end from whichever software they’ve reverse engineered,
There is no product support, and there claims are crap!
The specs are random stats bolted together such as “Wifi 5.0, Automotive chip in inside” 5G (it has no LTE function btw) ”
The unit i had had the software from a citroen installed, you cant update it, i certainly tried
In short – its a Turkey!!!
