nuvi 40 and 50 software version summary

Probably you made something wrong because it's a normal and safe method to update software in nuvi

@EdC
I'm sorry to hear you've had a problem but i agree with catymag that updating software from the card is usually very safe. I'm guessing that your unit lost power while updating or the problem is coincidental and unrelated to the update. The USB connections in most units can be repaired by reflowing the solder connections. Sometimes that doesn't help because the problem is on the board itself. Failed USB connections are a very common problem on xx and 1xxx nuvis, particularly the 5" models 50 and 14x0, but 30/40 and 12x0/13x0 and even 2xx/W can also suffer. I have a couple of units with re-flowed USB sockets which still charge but have no data transmission because of some other fault, probably failed component on PCB. I can backup and update everything including voices, maps etc by using text commands from the card, it's a little cumbersome but the units are usable.

Reflow first, and then if you still don't have data open a topic in Garmin Discussions and we'll talk you through updating from the card.

Thanks for the kind words.

I had opened up the unit and found I could not re-attach the USB connector because some of the traces had been lifted off the board. However, I cut off the B side of a USB cable and soldered this cable's black and red wires to a ground trace and the trace that used to be the USB connector's +5V pin. I also connected the ID pin to +5 (otherwise it seemed to hang waiting for a USB connection on boot-up). This gave me a fully functional unit. I was able load maps and even custom PoIs via the SD card. So I'm very annoyed at myself for not quitting while I was ahead.

My problem may be related to the fact that when the Nuvi is configured like this it seems to go through a different boot process than when the USB port is functional. I don't doubt that in normal situations this method works. That's why I thought it worth warning others who may be trying to do firmware upgrades with non-functional USB ports.

Setting/System/About shows the Software Version is still at 2.30 while the Keyboard version is "Unknown" and the Audio version is "Missing" so perhaps the problem is that the update to 4.00 did not complete or somehow went haywire. I'll try disconnecting the ID pin and to see if the different boot sequence causes the gupdate.gcd to get loaded (no amount of power cycling or erasing user data seems to do it).

Otherwise I may have to resort to using ldr.bin and update.txt as I think you are suggesting.

Thanks again.

Hi, is this firmware affected by HWID? mine is 1513 and when I update using Launcher.exe from garmin, it only updated to ver2.30

I want to change the 50LM boot splash screen image, but 2.30 firmware from this thread is HWID 1350.

Your nuvi is an asian device, this is US/EU devices thread

**mramen** · 30th May 2015, 04:15 AM

Can you kindly suggest where to find for asian?

@mramen
You have answer and solution for logo flash P#89 here: [Only registered and activated users can see links. ]. Flash pack for your Indonesian unit is included with that post.

**Neil** · 27th September 2015, 09:32 PM

Sherms, you can flash your 50 with 52 firmware if you want to freshen it's look up, but you won't add any features only change the icons etc. [Only registered and activated users can see links. ].
