Update - main dealer fixed my problem by carrying out activation of 5F software update to activate the navigation. Diagnostics test cost £150 and this included the activation above. I googled 5F and found this:- “Here’s a clear explanation of what “activation of 5F to activate navigation” means, in normal language. What “Activation of 5F” Means In Audi terminology, 5F is the control module for your infotainment system (MMI / MIB unit). It is the “brain” of: Navigation Bluetooth Telephone Apple CarPlay / Android Auto Radio and media functions When the dealer says they “activated 5F”, it means they re-enabled or re-loaded the software activation keys inside this module. Why this fixed your issue Audi’s infotainment features (navigation, smartphone interface, voice control, etc.) are protected by cryptographic licences called FEC/SWaP codes (Function Enable Codes / Software as a Product). These activation files tell the car that: your navigation is licensed Bluetooth/CarPlay are enabled your features are genuine and allowed to run If the 5F module loses these activation codes — due to: corruption voltage dip internal glitch failed software update internal storage hiccup — then the MMI loads but features disappear.” Hope the above is useful should anyone else get the same problem. Thanks Dave

Thanks for your response Steve and Cliff. Steve - I thought about taking my car elsewhere but If I need an activation code and newer software then I'd probably end up going to a Audi dealership in the end. Cliff - It maybe the subscription to use the satnav and Bluetooth has expired but the Audi dealership I brought the car from never mentioned anything about subscriptions at the time of purchase. I just thought someone else may have experienced this message and how they ended up solving. Much obliged for your input
