For users installing these maps on compatible devices, the process generally involves the file directory structure:
| File Type | Extension | Role | Critical for Argentina | | :--- | :--- | :--- | :--- | | Map | .fbl | Roads, addresses, turn restrictions | Yes – ensure it includes provincial routes (RN, RP, RC) | | POI | .poi | Points of Interest (gas stations, gomerías , peajes ) | Critical – gas stations are 150km apart in Patagonia | | Building | .3dl | 3D landmarks | Nice to have (Obelisco, Perito Moreno) | | Dem | .dem | Digital Elevation Model (hills, passes) | Essential for Andes crossings (Paso Libertadores, Paso Puyehue) | | Phoneme | .ph | Voice pronunciation | Optional – but funny when iGO says “Salida a la izquierda” | | Speedcam | .spc | Fixed and mobile radar | Useful – Argentina uses both radar fijo and móvil |
