RemoteService Connect
Read full descriptionHide full description
RemoteService Connect connects your vehicle to your workshop for the duration of an agreed remote session. HOW IT WORKS • Your workshop gives you a session code – or a link or QR code. • Connect your iPhone or iPad to the vehicle with the cable, adapter or interface your workshop specifies: – Ethernet diagnostic cable on a USB-C Ethernet adapter – Wi-Fi diagnostic adapter – ICOM diagnostic interface, connected directly to the iPhone or iPad via a USB-C Ethernet adapter or in the same network • Over the Ethernet diagnostic cable, vehicles of many manufacturers with DoIP are supported as well – you simply choose the brand. • The app recognizes on its own what is connected. • Enter the code. While the session runs, your workshop can diagnose and code your vehicle as if it were on site. WHAT YOU SEE • Automatic detection of the cable, adapter or interface – and a step-by-step guide if something is still missing • A notice while your iPhone or iPad sets up the connection, and a notice if the connection to the vehicle is interrupted – the app reconnects on its own • Connection quality and your vehicle's battery voltage • A chat with your workshop – text, photos and videos • On iPhone, the running session on the Lock Screen • One tap ends the session at any time. WHAT THE APP DOES NOT DO • It never works on your vehicle on its own and only talks to it during a session you started. • Nothing happens without a valid code from your workshop. • No account, no ads, no tracking. SECURITY • Encrypted connections. The chat and – by default – the diagnostic connection are end-to-end encrypted between your device and your workshop. • Your workshop can additionally require end-to-end encryption and servers in the EU. YOU NEED • A session code from your workshop • The cable, adapter or interface your workshop specifies – for a cable or interface connected directly to the device, a USB-C Ethernet adapter • Keep the app open during the session – iOS pauses apps in the background. • Follow your workshop's instructions, e.g. switch on the ignition or connect a battery charger. The app is free and has no in-app purchases. Sessions are provided by your workshop.
