Discover Pro - Firmware

[phope]

Right, took a deep breath and went for it.... 

* I will take NO responsibility if you decide to do this for yourself and it doesn't work as anticipated *

Please do your own research before carrying out any changes

This was my software version previously. 0376, with hardware 5G0 035 020 E



Using the software link in the German forum thread above, I downloaded the 1.4GB zip file, and extracted all files to the root directory of a SD card - I think you'll need a card of 8GB or higher and I used an empty 32GB class 10 SDHC card for speed (with no other files on the card)

I also suggest you use a Windows machine, rather than a Mac, as OS X has a 'feature' of creating various hidden system files on the SD card which confuse the hell out the Discover Pro, and are a PITA to manually delete

With the Discover Pro switched on and operational, I then held down the MENU button on the headunit for 10 seconds to enter the service mode, then selected 'Software/Hardware versions' then 'Update", then selected the source as SD card



A few on screen prompts followed, followed by a screen that said this



I held down the power button on the DP to reset the unit and held my breath whilst it restarted, for what seemed an eternity

Success - I now had a screen that asked me what I would like to update, so just pressed all, and let it do the updates automatically

It does warn you it could take a long time, and not to power off the car or start the engine either.

In my case, it wanted to update 4 files

A number of screens like this then followed over the next 5-10 minutes





Followed by another restart screen



After another restart, this was the next screen I was presented with this



Pressed the summary, and had a list like this, which I take to show which software has been updated from my earlier version







I then pressed the back arrow, and pressed close, and had yet another restart screen prompt

When it all booted back up again, success

• No radio stations presets/logos lost
• No navigation presets/POIs lost
• Phone was still paired/favourites still stored
• Voice control still worked

Version info now shows as below, but for some reason, it now reports my head unit as a D version rather than the previously shown E

I'll try and pair my work Blackberry phone later, as it was one phone that was having hassles previously pairing - I suspect there will be no difference as my colleagues also have various Bluetooth hassles with their identical Blackberry devices across a variety of cars.

Overall, the unit does seem a little faster overall between changing stations, etc but too early to tell if there has been any benefit in doing this (compared to my previous version, anyway)

Interesting..is this nav pro only? Or would us with the poverty spec nav be able to do it?

phope - in a nutshell, what is the point of this? I'm not being tricky, I honestly don't understand. Cheers!

[phope]

The point was to see if there were any incremental updates to the head unit software (akin to Apple sending through updates to your phone or apps) that may have made a difference to a couple of small flaws

For example, my work Blackberry connects perfectly to my A6 via Bluetooth, but is very problematic with the Discover Pro - connection drops, poor voice quality, etc - software updates from VW (normally dealer only) may rectify known bugs in earlier software versions 

[Watts]

Thanks for that, I think I understand, if a fix doesn't involve my socket set then I'm usually all at sea!

Have you seen any sign of the bugs the 388 firmware is supposed to have?

Namely, not fading the audio when a sat nav comand is issued and a problem where the bass disappears when the volume is increased to 50% or more.

[Sootchucker]

Do you know if it matters it you have Dynaudio or not ?

Is there a different 0388 if you do ?

[phope]

I don't have Dynaudio so can't tell you about that

I've just tried the radio and media players on full volume several times - no change in sound quality

I'd need to check about the sat-nav announcements - mine has never reduced the radio/media sound when playing an announcement, but have perhaps haven't set that up correctly in the sound sub-menus to begin with

[Sootchucker]

Well as Phope said, it's quite nerve racking, especially as when mine eventually restarted, I saw the "welcome to VW" splash screen, then the GTD screen but no "Powered by Dynaudio" splash screen - I thought oh crap !

Happily, the unit re-started again and this time the Dynaudio screen appeared (phew) and this time everything was fine. The unit definitely seems a little quicker and everything works as it should. Obviously mine was a bigger leap than Phope's units (going from 0200 to 0388), but mine still only took about 35 minutes, with the longest part appearing to be the loading of the TTS Voice files.

Dynaudio is still there and still sounds fantastic. I've also noticed that if I'm set to manual zoom on the maps (rather than autozoom), and then start a route, it used to default back to Wolfsburg in Germany, but under 0388, that bug appears to have gone/ I'll do some more testing over the next few days.

Mine showed that 4 updates were required - how many for you?
