Kendwood DNX 5330BT - Map Update

[ghosam]

Hello Folks,

Need your expert advise and guidance for updating the Map and the garmin software on the Kenwood DNX 5330BT HU.

01. How to update the Garmin navigation software on the Head Unit? I am currently running a pretty old version from 2013.
02. How to update the maps on the SD card? and Ensure that my Junction view can work?
a. Currently on the SD card there is a Garmin folder and inside I have have GMAPSUPP.img file which is also 2013.20 (malaysia/singapore map) and nothing else.

Background

DNX5330BT was a used set bought from my friend and he mentioned that the map on the SD card is from garmin but unlocked ones.

One more Question, Lets say if I purchase City Navigator® Southeast Asia NT Part Number: 010-D0974-00, will my above 2 questions will be addressed?

Thanks in advance for your guidance to update my kenwood dnx5330bt with latest version of software and map.

Cheers,
