So figured that I have b unit, but cant seem figure out which firmware i have. One question i can't seem to answer is what benefits ill get for upgrading? Not a naysayer but interested..

Over the years new firmware has increased the size of SD cards that can be read, sped up device performance slightly, changed the boot screen (nicer imo), allowed you to use voice control to enter a new destination while driving (works well), and recently added Radio Text (song names, weather forecast, etc) on the radio screen.

Just gotta remember when you do decide to take the plunge that your B unit can only upgrade so far (punching above its weight).
Definitely can't use the latest version floating around!

Turn unit on Hold SETUP down till screen changes to the two radio bands and Version informationOriginally Posted by Darks RS
Press that and it will go to black and white screen and will tell you on one line
SW version XXXX Thats the Firmware
Further down it will say MAP version XXXX
Now you know
You can only update so far in the Firmware on that unit as per the Sticky but can update to the latest map

FW V Question:
At the beginning of this thread it says "Firmware 421x - Link" but the link downloads "AU_4120_FW_90_5_5" is this a typo? Which version number is correct as the latest?

awesome kamold thanks. All updated to latest 4120 FW and 7970 v6 maps (confirmed in secret menu). Having trouble getting a satellite tho. Went for a drive but that didn't fix it, just shows a blank map. Have had this issue before as have others but usually a short drive fixes the issue. Any advice?

Normally does sort itself out when you're outside!
Did you load some custom POIs as well? They do take some time for the unit to digest on first install.
Have you looked at how many satellites it's locking onto (when outside)?
Might be a dodgey antenna or the location you have it (assuming it's a puck antenna).
If GPS reception is fine, then which version unit have you got (under a proper VCDS scan)?
Might just be an older and slow unit.

I tried to update my 1T0035680C from SW 2760 to 4120 today and it seems to get stuck.
It picks up the SWL-CD and begins the install then after a reboot or two it searches for a SWL image, and then says "not a valid swl source"
Should I be able to update straight to 41xx from 27xx? or should I try an 3xxx or SW Downgrade first?
