TMC is the other one they leave off and short change you on the Navigation FeC for repeat business I assume. Then when I did get the FeC adjusted it messed up TSR so it operated in KPH and not MPH so told you, you were speeding at much lower speed. Took them about five hours to solve that. Reckon that was because they adjusted the navigation FeC when the maps were not valid or their patch didn't adjust that as well since it was designed for Europe / not fully specified car with TSR.
Retrofitters can be sometimes be like the poor IT technician that leaves you with a bunch of problems that you sort out yourself after or you have to keep going back till they sort it (no Microsoft accreditation for their work
- fine if they sort it out in the end or you do). Getting the navigation FeC corrected didn't cost me anything apart from two nights away and driving across the country. A chargeable firmware update was dangled but given I was happy with the firmware I passed on that, took their free aftercare only.
Ateca 2019. 1338 is what I'm on shifted from the 2016 one.
Basically I drew up a check list from Walones experience and checked before I left, TSR was the new one which you couldn't check till you were on the road. Had much driving round Doncaster to check it. All good.
The story goes that the firmware isn't modded, its the coding that is changed. Its that coding they dont put back that the causes the issues. The first time it was done they took a dump of the coding as is and it was that they put back after the firmware update with the short changed navigation FeC (was suppose to be unlimited like VW and Skoda that's achieved by putting the Hex in the FeC high) that offered one year of updates. Second time around to have the FeC adjusted the solution to the TSR issue was to restore my settings from the dump they took a year before. First time round they patched into the data flow of the car using the front camera port to read that. It's that which was used to manufacture the update that was delivered back down the line and into an SD card then inserted. Then the VAG tool to make further adjustments.
That's when I derived the ready reckoner on the Seat navigation FeC so you knew where you were so whether you had Mapcare or not you knew your limits to the high updates being imported. You can check what your retrofitter has left you with or if you have limited Mapcare where you are on future updates.

So it must be that if you buy the firmware from your "Turkish" man you are left with resetting the coding yourself via VCDS, the professionals, dependent on how professional they are (No VW accreditation
) should take a copy of the coding and restore it back, if they don't, that's when you get left in a pickle. The personal touch of driving to the place and not leaving till it works has much going for it.
