@chrisp looking at Software Version Information page within MyLink will show what’s loaded.
These two pages have various items listed but there is no clear correlation between the part number and it’s function (be it some firmware object or data object or however it’s partitioned).
Having said that,
@RoganJosh seemed to be one of the first to get map updates done on his VF and sadly he needed to take Holden to small claims to get it done. If I remeber correctly part of that settlement was a Holden document that listed the map version as always being the third part number from the bottom of the software information list.
So taking that into consideration, my Motorsport which had recently had its first service done, also had a map update done where the map data part number “84019250 Version 30.11.0F.11” was updated to map data part number “84160883 Version 30.12.10.11”. This was the only change reflected in the software version information pages.
So from my perspective, it absolutely seems that map data 30.12.10.11 is the latest unless new maps were released in the last month. Just as an FYI, this map data version was released around March 2018.
If all other software items are the same as before your service, I’d say you’ve been stiched up. If something else was updated (system firmware for example) then the tech may have simply been confused as to what object was updated and charged you thinking he updated the map data but this does not seem the case as nothing has changed pre/post service.
As a side, firmware correct faults so should be free under warranty. They should also be free outside warranty since it is faults being corrected, not some new feature being added like Apple car play or android auto (which many would line up to pay for su h an update).
So, get them to refund the charge and as a guesture of good will get the dealer to provide a free map update whenever Holden gets around to releasing the next one (later this year or early next year).
