Equivalent META codes

In my search for meta's for new maps, I read a few interesting postings about equivalent meta's. There are a few postings on this board, but I read the 'Special V980 maps' on another forum: (Mod note: links to other forums are not allowed)

Now I think I succeeded in patching the map Western_Europe_980_7899 by tracing back to an equivalent older Meta. At least, FastActivate v23-12-2016 reported it as OK. So, I hope that means it is valid...

For my TT Go (a TOYOTA II on original navcore v7.828) I was looking for a map version v980.7899 as displayed in one of the many posted 'what-map-works-on-what-navcore-tables' like [Please Register or Login to download file] .

That one says: The Meta for 980.7899 = 975.7689 = 970.7468. With that in mind, I looked for the v970.xxx table and so on. Just until I found a map with a known Meta. So, I followed the route below and got:

1) 980.7899 = 975.7689 = 970.7468
2) 970.7468 = 965.7252 = 960.7057
3) 960.7057 = 955.6745 = 950.6491
4) 950.6491 = 945.6176 = 940.5966
5) 940.5966 = 937.5916 = 935.5744
6) 937.5916 = 935.5744 = 930.5560
7) 930.5560 = KNOWN !!! (topic15548.html)

So, the meta for the old:
; Western_Europe v930.5560
12 0B 49 96 00 CB 12 71 71 ED C8 50 06 28 89 AB Western_Europe-913.meta

would be exactly the same as for the new:
; Western_Europe v980_7899
12 0B 49 96 00 CB 12 71 71 ED C8 50 06 28 89 AB Western_Europe-100937.meta

After adding the code to the 'Integrated_meta.txt' used by FastActivate.exe, it reported "Western_Europe-100937.meta.dct = OK". Unfortunately the map doesn't seem to work on my old TT with aged navcore.

So, before posting this 'new' meta in the thread Meta Codes 980 (maps-v9xx-f179/meta-codes-980-t19324.html), I would like you to check this out as well.

And if it works for you too, would it be a good idea to open a special thread where users can post their found 'back-traced' meta's?

Thanks.

I tried to do something very similar. I used known metas 980_7898 and 980_7971 for unknown 980_7895. Fast Activate worked with both of them. But alas, with either of them the map is not working in TT device.

Give an example.

It is a differend story and post 1 is not correct.
Activation of maps with equivalent metas. If you have a map that has no meta,
you may be able to activate it if there is an equivalent meta.

1.Benelux_980_7971 metacode for this map is known
2.Benelux_980_7899 metacode for this map is not known
Forget the meta code

Download both maps
Delete the Benelux-100937.meta file from map 2
Copie the Benelux-100985.meta file from map 1 to map 2

Now you can copie map 2 to your device and activate the map with FastAktivate
(the metacode from map 1 who is know is been used for aktivating map 2)

There are more then enough metacodes known so it can only be usefull in the beginning
of new maps. How to known wich meta,s you can use as a equivalent I don,t known

I tried it again for Central_and_Eastern_Europe_980_7895. I replaced its meta with Central_and_Eastern_Europe-100936.meta from Central_and_Eastern_Europe_980_7898. Fast Activate is OK, but the map is not working in TT device.

Central_and_Eastern_Europe-100936.meta is not an equivalent meta.
To my knowledge there is no equivalent meta availble for the Central_and_Eastern_Europe_980_7895
