I am at a point of complete frustration with my attempts to download an updated nav disc file. The only other Prius owners I know are no more technologically inclined than I am and thus are no help. I have read the thread on here about the Camry update, but haven't been able to find any complete info about the Pruis update.
Can someone walk me through how to accomplish this successfully? It would be much appreciated and I promise to pay it forward .
Thank you!
