I don’t know how to choose correct update..

Might happen that you visit our shop and you see lots of different update.. you might be confused which you should buy.

Will try to help you here, however you can always contact us with your current full firmware version.

What’s my current firmware version?

We have created full article about how to check what mmi you have, so will not duplicate that article. Please take a look here how to check your current firmware and map version.

How to choose correct update?

Ok so you know what MMI system you have, now you can go to the Store, select your car, select your Area and look for similar numbers that you have already.. I mean, if you have now HN+_EU_AU3G_P0029, you need to look at HN+_EU_AU3G which describes your MMI system.. you need to choose same system beginning at HN+_EU_AU3G (in our example!).

If you have Mib2 system for example in Audi A6/A7 it starts like: MHI2_ER_AU57x OR MHI2_ER_AUG11 in this case it can be mixed only AUG11 can be replaced with AU57x.

You cannot install MHI2_ER_AU57x on Audi A6 which has HN+R_EU_AU3G because that’s completely different systems.

Please note that only Audi A6/A7 can be replaced from AUG11 to AU57x.

In Audi A4 we got more choices.. but the same rule.

We do have Hnav_EU, HN+_EU, Bnav_EU, MHI2, MHS2..

So if you have MHI2_ER_AUG22 you can only install firmware starts with MHI2_ER_AUG22.

Every our product got compatibility list, but in same year could be installed few different MMI.. it’s very important to check before you place order which software version you have.

The best method is to check on Red Engineering Menu (every MMI got access to it, do not need to enable via script or vcds) I know it sometimes tricky to get in there, but you need keep trying.

Is there any tool which will tell me about latest updates?

YES. We have created a special tool, where you need to insert only full firmware version and it will show you everything what we have. Click here to check our tool. You need to insert your full current firmware version, for example: HN+R_EU_AU3G_P1234, MHI2_ER_AUG11_P1234, MHS2_US_AU_P1234

What about the maps?

Similar to software, you need to get know what type of MMI you have and then choose correct maps. For example if you have system HN+ or HN+R (which means MMI 3G Plus) you ned to find MMI 3G Plus maps, if you have Hnav_ then look for MMI 3G High maps, if Bnav then for MMI 3G Basic maps, MHI2/MHI2q then for Mib2 maps, if MHS2 then Mib High Scale 2 maps.
