i will trye, so just for one test, because , old map inside give nice backup if i lose my external SD or broke this SD


so if you put put de same name map inside and SD, gps dont like start ?

so i made one test, i using City navigator North america NT 2014.40 without Mexico in my SD card, and ill made City navigator North Americ Nt 20140 Mexico only inside my gps gmapprom.img
ill give my feed back after

You do not have any problem using this way. File name is not matter but only gmapsupp.img on SD is available and maybe is not available gmapprom1.img inside. We use this method many year... Good luck!

As usual you make me justify my uncertain memory G .... [sighhh ...]

Here is a US 360 with NA 2014.20 ALL [1.88GiB] gmapsupp on the SD card; Internally it has Raratonga gmapoem [not de-selectable], AUNZ gmapsupp, Norfolk Island gmapprom, Bangladesh (BGD) gmapprom1:




gmapsup2 won't work internally, and of course gmapsupp is the only name usable in SD. gmapsup1 does not work in SD unlike as enabled by later US/EU fw for 2, 4 and 7 series.

Absolutely not a problem even if identical parts of the same map is present both internally and externally proved the version is identical. This is, you could have 2014.40 US & CA internally and 2014.40 US & MX externally and there wouldn't be a conflict because the duplicated tiles are identical. Mixing versions with no duplicated tiles will be ok [e.g. 2014.40 US and 2014.30 CA & MX], doing that with overlapping areas can bring you grief very probably though in actual use, but won't prevent your unit from starting. I had a problem years ago 'in the wild' with the OEM US lower 48 map teamed with a later version of CA 'cos i forgot that the CA map also included the US border States. Made 'Shuffle off to Buffalo' quite a trail. Fortunately the CA was on the card so just took it out. On the other hand, i once bought a 1390 from a bloke who had travelled all the way from Perth to the Eastern seaboard of AU with an old version of Sensis AU onboard and a new Navteq AU on a microSD with both enabled. He said he hadn't had a problem. I didn't really believe that so used it for a few days the same. It ran erratically and the routes were strange but it didn't freeze or reboot. Took out the card and hard reset it and it ran perfectly.

Perfectly acceptable. That will work for sure as Giomen said.
