To know the map that corresponds:
Review the of the series, know the color of the maps that are used for our navcore number.
Check to know which maps have a meta code to be activated.
As an example:
Navcore greater than 9010 (9510 or 9057), you are served all maps, green*, dark green*, brown and blue (in that order)
Navcore from 8200 and up to 9009 only brown and blue maps.
Navcore lower than 8200 only blue maps.
My opinion...
*In the case of gps with availability of IQroutes and navcore greater 9009 (One Iqroutes, Start, Ease, XL Iqroutes, XXL) that are devices with 64 mb of ram, without microphone asr, TTHome will indicate you to place green maps but I prefer to install the browns if you do not need hnr, because those maps do not carry cspeech that these devices are useless.
You can also put the green maps and remove those files.
@Orni thanx for clarification of the Compatible Chart. Now after a closer look at the chart i see that the answer to all my questions was already in the Chart.
As promised here the result of my test:
Downloaded the WE 1015-9160 which had a meta, installed and activated -> ok, works great
Downloaded the WE 1015-9104, no meta available, installed, copied the metafile from 9160 into the 9104 and activated -> OK also works.
Conclusion for next update first look for the meta and use the appropriate method; @fredderf exactly what you wrote in #5 sorry!
Many thanx again to you all for the support
