Road Map TAIWAN Premium 2020

[py1]

Hi Pat,

1. I've downloaded the map but the file size is only 533.6MB, I'm not sure if it's the correct file or not. 
2. by your instruction, the map files should be updated through the USB drive.  Unfortunately, my CIC-1B system is Year 2009 without the USB access equipped and the only way for map upgrade would be the DVDs.
3. Would you please advise the process for going through the map upgrade by DVD or need other map files?

Thank you
