Right then a quick update on the 1300 firmware after having a play around with it last night.
ChangedSpeed displays operational on the Nav screen (i.e it tells you the max speed for the road you are travelling on).
Ability to set blocked roads on the Navi
Quicker response time to touchscreen presses.
If clock is set to display (in setup menu), then with the ignition on and the RNS switched off, it will display the time.
Ability (on my unit anyway) to use 16GB SDHC cards (didn't have anything bigger)
"MEDIA IN" button on RNS now changed to "MDI"
Showing the HDD capacity now shows a rather nice Pie Chart rather than the single coloured line from before.
Not changedStill only 4 digit postcode I'm afraid
No issues that I can see with MP3 files not starting where left off. tried it with MDI, HDD and SD card and they all work fine.
No Resenberg Syndrome. Picked up my position immediately.
Start-up time not changed (i.e. a tad slow) but as mentioned, when booted, touch screen operation does seem faster (although this could be a placebo effect ?).
So far (at least - no issues with battery drain, although to be fair the car was only left overnight. However upon starting this morning, I did get the "Welcome to VW Navigation" boot screen, which seems to indicate to me that the unit had fully shut down. Took about 15-20 Seconds to fully boot up (i. e until the map screen could be displayed and the "system starting" colourful screen disappeared.
Also, as mentioned, both the music files on the Navi unit and the Maps, plus all settings (Radio presets, bass, treble settings, and colour scheme) were unaffected by the firmware upgrade.
If I find anything more, I'll post up.
Cheers
