thanks, As per my information, all GPS devices are licensed with SD CARD CID (unique numbers) and on bootup all GPS device reads the CID number of the SD card and then verifys it with the license key available in your SD card. if they both match MAPs will load otherwise it shows an error message.
As you are providing SD card with the maps which Honda navigation accepts it i am assuming you have an idea about how to extract the CID # of the SD card.
if you know pls let me know the procedure ! ! ! ! !
