Hi guys,
I have just this week purchased from Johnny Appleseed GPS Garmin TOPO V6 Including Hema Australia. Garmin genuine version. I am happy to upload it to share with other members. Please let me know if you are interested in getting a copy and I will organize it.

My question is please,

When I received the MicroSD card, I plugged it into my Windows PC to make a back up of the card. I ...

Hello everyone,

I was offered an old GPS V very cheap. I never had a handheld, so I wonder what to expect? Can I update the maps on it? How good - or bad - is the screen and overall performance? Not a lot of info online on this model.

I appreciate any thoughts or info on it.

Thanks!

Using Mapsource with a lifetime map update I created an .img map of SE United States and installed it on my Garmin unit. The map is found, but does not show streets, etc.
In the past, I have had no problems using this technique. Any suggestions?

Hi everybody,
a couple of years ago, I managed it (somehow), to remove the satellite pictures from the bluechart vision files for my GPSmap64.
However, I would like to redo it again, but I have forgotten how I did it. I think, I had to extract the img-File, delete something, and
merge it again.
Does anybody know in detail, how to do it?
Thanks in advance!

Hi everyone,

Does anybody know of any Garmin units of present production (i.e. new units) that will accept an external antenna so they actually have an input for one?

My units with inbuilt antennas play up shocking with not getting satellites and only displaying half the info or completely wrong info if there is any info at all.

I have ordered a re-radiating antenna to see if this helps and in theory it should but ...

Hello everyone,

Just updated an old nuvi 1300 to latest FW 6.30 and installed an updated map - aside this new one, it only has gmapbmap.img and gmaptz.img in the internal memory, and JaVaWa Device Manger warns to not remove them.

Thing is, when using the nuvi, it is very slow to load the map - to "draw" the map in the screen, if that makes sense, not the initial load. I moved the map ...

I am looking into various City Navigator maps for Europe / Africa & Middle East but noticed no support for Asia. Contacted support and they said it is unsupported.

My trip will begin in Singapore and head north to Malaysia, Thailand, Cambodia, Vietnam, Laos, Myanmar, India, Nepal, Pakistan, Iran, Turkey and unto European.

There are Thai / Malaysia Maps but it seems to only fit certain Garmin for that region. What gives? I have an ...

Hi.
I have 2 Garmin Nuvi 1340 satnavs
I have downloaded the latest Maps NT2021.20 from here.
Have loaded both the say navs with the appropriate files/maps in the same way.
One appears to work ok.
The other gives a message "Can't unlock maps" .
I have updated both using Garmin Express.
I have checked the content of both sat navs and cannot see any difference between them?

In desperation i copied all the files ...
