About 3 years ago I bought a GPS PNA from Ebay with IGO 8 installed. Recently the SD card became unreadable, so I have lost the software. Tried to install other IGO software but didnt work. Can I somehow format the ROM (I am a newbie on GPS software/hardware) and install a Nav software from scratch? Switching the PNA, the "desktop" consists of 6 icons - Navigation, Music, Photo, Ebook, Video, System. GPS specs: ROM Version: 66.jxx.9.3.18 Processor: Atlas III RAM Size:64mb Software Version: 2.11.8.7.10 ID: 2dba6c75010000ad
