MediaNav Test Mode Code Generator

WARNING: Test Mode is a powerful diagnostic and engineering system that allows booting into MICOM Manager and Windows CE on MediaNav and MediaDisplay navigations used in many Renault, Dacia, Vauxhall and Nissan vehicles. It makes it very easy to brick or cause expensive damage to your navigation, and should only be used to enable well-tested functions with well-known implications. The free information below is presented as is, without further support or advice on enabling features, and we bear no responsibility for any changes made or damage incurred while doing so. Take extra care to press the right buttons, and if ever in any doubt about what you're pressing, don't press it.
