Thanks for the offer guy, I have it booked in tommorow to do the update to 900, though by the looks of the firmware the GEMMI was introduced around the 614? ish mark. as IT says i was reffering to the radio 2g rather than mmi 2g. others have led me to believe that it will work ok on the 2g mobile network so will see how it goes.

Ah I see so the internal telephone module itself I did not realise they had 2G in terms of data ... shame there locked to 3G .. you would think with 4G service now Audi would use the 4G network. .. would make on board WiFi ect much more useful.

I think there is a way to change the modem to allow 4G but can't remember how.... might make that my next mission to convert to 4G :D

I see no reason why it would not work +++

I'd imagine it will just be a tad slower to load than 3G ... but then the 3G is not all that fast anyway... when using online services or Google Street view it could be much faster

if we wait a while i imagine the next 5f unit will have 4g if it hasnt already. there is a firm down south near hemel which can change parts of your 5f to upgrade it to 3g for a few hundred quid ive heard.they also specialise in bricked units.

Depends where you live or drive. We don't have 4G signal either where I live or work but in the nearby towns which I have tested 4G is much slower either because signal is poor or because it's overcrowded. Every time I tested I was getting 1-2Mbps if phone left on auto and connecting to 4G and 5-14Mbps if forced to only use 3G. And it seems battery lasts longer as well when forced not to use 4G.

I used to get a faster 4G mobile connection on the Brighton mainline trains than I had through my cable broadband! Connection can be flaky but when I lose 4G I usually lose all connectivity including for voice calls....

The A7 I have at the moment supports LTE (4G), the latest 5F for the A8 does not.

You can update the mobile chipset within the 5F unit, but the later chips use a different form factor so it get's more complex than just soldering!

The good news for you is that google maps will work fine on 2G mobile connections +++

All done, just back from Audi - updated to 0770 - couldnt wait for them to do the 0900 - can do that myself if i want to just didnt want to go through all the updates to get to it.

Can confirm they went from 0065 to 0770 in 1 hit, no problems - google earth came up as soon as i put in the sim and connected

google maps worked instantly no loading or lagging - the street scene picture thingy takes about 8 seconds to fully load, seems fine to me on 2g

have yet to look around at any other changes, i ncan now see the google connect icon on the main screen, can choose google maps from the nav settings, and now have a menu for wlan

Great news +++

Great news.... How long would you say it took end to end ?
