Doesn't work the majority of the time therefore car features also have limited functionality. I didn't buy a 2022 Mercedes to end up with unreliable features & shouldn't have to uninstall/reinstall an app continuously. Called the help line - advised to reinstall then send screen shots. When I reinstalled the remote start feature wasn't even there to screen shot anymore. No response from Tier 2 for >3 days. My overall impression of Mercedes is NOT positive and I definitely regret this purchase.
