type of MMI. These are the Audi A3 (8P), A4 (B6 and B7), A6 (C5), TT (8J), the R8, SEAT Exeo and Lamborghini Gallardo - when fitted with the RNS-E DVD based "Audi Navigation Plus" system. Whilst appearing to be a similar layout, and operating in a similar manner, these two systems are very different, are unable to share mapping discs or software, and are not able to control non-ICE functions (such as climate, convenience or suspension settings). On members of the B8 family of vehicles (the A4 (Typ 8K), A5 (Typ 8T), and Q5 (Typ 8R)) without full navigation capability, Audi does not describe this infotainment system as MMI, although an MMI-esque control dial and function keys is provided on the radio/CD head unit. MMI Generations 2G through 3G+ The MMI system has been improved over the years and now features internet connectivity through MMI Connect introduced in recent models. Issues While seemingly intuitive and user-friendly, MMI can be difficult to operate when driving. Attempts have been made to improve access: the MMI 3G features a new Joystick on the central knob to make it easier to for example input a destination using the navigation map. However, the issues remain. The Audi Q5's MMI infotainment control system is especially difficult to navigate, partly due to the location of its controls low down on the center console. Software updates MMI 3G and 3G+ systems have to be updated by an Audi dealer. The MMI 2G firmware can be updated by car owners. MMI 2G systems can be updated via a CD containing the firmware update. Navigation maps are read in real time from DVD drive located in the trunk. MMI 3G and 3G+ systems can be updated by using a SD Card/USB/CD/DVD containing the software. The total update process can take approximately 1 hour and 45 minutes. Once the updated software is applied it requires a PIN to re-activate the navigation system. To enter the MMI software update menu, the [Setup] and [Return] buttons have to be pressed simultaneously for 5 seconds. This menu also enables import/export settings to USB or SD Card, the settings are saved as an AES encrypted zip file. Software version format varies by MMI system type: MMI 2G: SW: XX-XX XX.X.X XXXX MMI 3G Basic: BNAV_XX_XXXXX MMI 3G High: HNAV_XX_XXXXX MMI 3G+: HN+_XX_XXXXX [A1 A4 A5 Q5 Q7] HN+R_XX_XXXXX [A6 A7 A8 Q3] MMI RMC:
