Not useless for me - does everything I want. It's a car not an entertainment centre. Works well with my phone & I can use Google maps instead of the built-in sat-nav if I wish. I'm older (73) than the average poster on here so doubtless have different needs.
OK, just an update, got full link installed yesterday, all good apart from few things, when tried to use mirror link with my new phone Samsung A71 said won't work as stopped on June 1st? Got android auto to work, also only recognises USB lead now and then, going to order another 1 from Samsung direct see if that helps, appreciate any advice or feedback, know I shouldn't complain as got fitted for free,
