Thank you for the file. As I said I had PouchX's 3.61 on my nuvi. But my problems started today when I tried to update to 3.70 by myself. First I downgraded to nuvi 265w 7.50. Then I tried to update through updater.exe with nuvi 465t 3.70 made with RGN Tool. The update seemed to be successful, but it was not. After many tries, I have now "System software missing". Updater.exe is recognizing my device as nuvi 465t, but says "No updates are available for you device". What to do now? Can somebody make cure nuvi 465t 3.70 firmware? I tried with RGN Tool, but nothing happened. My HWID is 0827.
