Hopefully I won't get embarrassed by what I said. It's the VW mib2 standard that has a variation on it that came to light when people were getting Inrix to work on it.
Updating the inbuilt Mib2 Satnav / Mib2 tricks and Mib1
Just updated to latest maps. First time I've updated them since I got the car. Sat nav works fine so far, new roads in my area now included. Scanned my car with carista and car scanner pro app and getting a Navigation database not enabled error code. As I say, it seems to be working fine, just...www.seatcupra.net
Delphi units were the issue. Same mib2 standard map but how it reads the contents different so the fix didn't work. That fix only works for the old Here Maps version. Mib1 is just that coding change of TMC group from 15 to 14. So mib1 you get new maps plus working TMC.
What you'd do in anycase as a controlled experiment put your existing working map on the new card and check. Having passed that move over the 2023 map.
Seller got back, apologised said he did the ad based on the info he gets from his supplier., said send it back for full refund. I said I'll send it back but can we to a "swap" for one of the MIB2 cards...So we'll see....
I'm "doing" 3 cars ATM.
Mine which is 10yr old MIB1...so as you say whatever MIB2 card I get, I'll remove the files & place my working VW 2020/21 maps & DBinfo file on the card to make certain the card works.....then delete those from the card & install the 2023yr maps (which I have already downloaded from mibsolutions), & do the DBinfo part number hack...
I'll have to whip out VCDS to do the 14-15 change in the TMC group....
Then I'm working on a mates MIB2 golf from 2018yr..so I did a maps update from the VW website which went all ok....as we chose a 9GB UK/EU maps bundle as he has a 16GB card.....MIB2 unit needs a firmware update having put the SWtrain number for the unit into mibhelper....I have downloaded the latest FW from mibsolutions also...
I also have a mate with a 2020yr T-cross with MIB2 to update the maps & Firmware on also!....will be busy!.....
