Update nüvi®50 to nüvi®50LM SG/MY firmware

[khanuar23]

Hello guys
After living in Shanghai for 3 years, it is time for me to move back to Malaysia by the end of July. I bought nüvi®50 which is designed for users in mainland China. Is it possible for me to convert my nüvi®50 by updating the firmware of SG/MY nüvi®50LM into my device? Is it illegal?

Your default firmware can load our CGS Map compiled MFM maps via this link : viewtopic.php?p=123970#p123970

Yes, I know my device can load MFM maps and it also can load City Navigator Singapore/Malaysia NT 2012.10 from Garmin
but it cannot run Sg/My JCV feature because different firmware. Here is the screenshot.

You will void warranty / support as this considered illegal mod.

I think better stop thinking to convert the firmware for the mean time.... very risky business...hehe. Lets other do first, never mind the JCV feature, without it can still navigate....

Keep the China firmware. Unless things changed, the China firmware allows you to use China maps without positional offset. Global sets sold outside China will suffer positional offset as much as 500meters when using Garmin China maps

Yes, China set will show accurate position with China map without offset, I downloaded one tile which is Shanghai map from http://garmin.openstreetmap.nl/ and use with my China set and no offset. I am not sure whether this map offset already adjusted or not. How about using my China set with My/Sg map or other map, will it have offset?

I used to own a Taiwan Nuvi 765 to use in MainLand China. Swap that for a localized 765 for use locally to get JCV/LA.

Your Nuvi will work fine in other countries with no offset. Only use in China is unique due to offsets imposed by Government rules
