The newly installed camera simply was not in the database.</p> <p>After digging into this product category, I found three fundamental problems:</p> <p><strong>First, dashcam map data never updates itself.</strong> The built-in camera database is a snapshot from the day the device left the factory. Updating it means hunting down a file on the vendor&rsquo;s website, pulling out the SD card, and flashing it through some buried menu. Most people never do it even once, so the data stays frozen in whatever year they bought the device.</p>
