Hi all Experts,

please teach me how to upgrade my Holux 6210+ from Papago X3 to Papago X8.5

My Holux is running on wince5.0 , com 1 , baud rate 4800 and I've downloaded the necessary files and maps from Monster Sifu.

Do I just replace the whole file system or ?? I do not have any SD card inserted to my GPS so the main directory is located in the GPS itself. Also, since my stock battery has bloated, so I had discarded it and now GPS can only be ON when plugged in to my GPS cradle in the car.

Otherwise when plugged to USB on my PC, the OS will not turn on but only showing USB is connected.

Can anyone teach me how as I am really clueless Also, is it true that I can buy BL-5C Nokia Battery as a replacement batt
for my Holux 6210+?? Anyone can verified that?
