Hi, Everyone. I just purchased a used 2015 ES300h and I need to update the navigation system map. My old HS250h required that the dealer do any nav updates, but my new car has a micro SD card slot so it looks like an update should be pretty straightforward. Is it possible to buy the card somewhere for this GEN 8 system and install a new card myself? My local Lexus dealer is saying I have to buy a replacement card from them for $210 then pay to have it programmed. Any guidance, suggestions or options would be very much appreciated. Thank you!
