Still works? I don't know nor am I going to try it-

Combining maps of the same area,m whilst do-able, is likely to cause a navigational nightmare.
Garmin have told me the same and also not to have two maps enabled for the same are at the same time as this can results in weird routing calculations. Tho sets of good data, joined, will most probably result in routing gobledeegook!.
In the Montana you simply have two (or more) img files and you just enable the one you want. simples!

If you are upgrading, I would recommend Garmin's Montana. Garmin have done a very good job with it -
I'm not a fan of updates but today's one brought new options that I find very practical. see above-

Time to 'take Ze plunge mon ami' !! and get one! ( I should be on commission- alas......)

HEADS UP - A Spooky development!
 

Here is a very Spooky :scared: development!!

Spooky has found by accident that you actually can rename a gmapsupp image anything you like - for example 'India' or Thailand etc as long as you do not alter the file extension!
This means you no longer need to rename the files gmapsupp1, gmapsupp2, etc.

Just to be safe, before I posted this up, I checked this with Garmin and they tell me that this is fine and works on the latest units.
Works on Montana and the handheld 62S - I did not ask about other units.

This is particularly helpful when saving OSM maps of various parts of the world as it identifies them clearly when the micro SD is placed in an adapter so that you can read the content on a PC and not overwrite the wrong file.

Congratulations to Spooky for finding this little treasure!:thumbup1:

Hi,

Is anyone using a Montana in a 4x4 with a lot of "stuff" - RTT or whatever over the cab? How is the reception?

Do any of the mounting brackets allow for the use of an external Ariel? Anyone think they are needed?

Merv.

Yes Merv
Yes, there is an output for an external antenna - needed? mmm hard one that- if in vehicle with heavy shielding maybe?
Yes, I also use this in my 4x4 without any problems without an extra antenna-and I have VHF/CB etc on board
Yes the montana automotive mount allows access fore the cable
No, no problems of signal loss at all. (tunnels and places of the sort excluded!)

I have used this a lot in my land rover that has a very vertical screen and you do not need an external antenna. I did on my previous Garmin 176c. So I would be surprised if you did need an external antenna. This unit seems to have a pretty sensitive receiver.

But only if the maps are all routable! You can combine a routable road map with a non-routable topo map and that should not cause any problems.

I can confirm this. We were in Slovenia in the summer and the Adria and CityNavigator maps caused the unit to go mental when i accidentally forgot to disable one. I eventually managed to get it to disable one set.

This is only an issue when you try to calculate a route.

I have noticed odd behaviour between Explorer and Birdseye layers, where you don't get the correct detail as you zoom in. I have a toggle shortcut to work around this.

The following questions will give an idea of my level of knowledge, but here goes:


With the Montana can you design bespoke routes on a PC utilising Mapsource and transfer them to the unit?

Garmin appears to offer automotive and marine mounts with a power and audio cable, can it then be hardwired into the 'bike's power removing the need for batteries?

Many thanks.

You can use either map source or basecamp. The latter has profiles which allow you to change the behaviour of the program. EG Walking, driving, bike etc

If you hard wire the device it no longer uses the battery, The battery has a very good life of about 14 hours in my experience, it will also takes aa batteries which is useful. The wired connection provides more than just power. EG Audio.

Hope that helps

MONTANA MASTER RESET
Procedure:
1. Turn off the unit.
2. Press the top left hand corner of the screen with your finger.
3. Keeping your finger in the corner, turn on the unit.
4. Keep your finger on the screen, until you get a message ?Do you
really want to erase all user data.
5. Select yes, and follow the setup instructions
6. Now leave the unit in clear view of the sky, outside is better, but a
window sill or glass roofed conservatory will do.
7. Do not move the unit for 30 minutes, this is to allow it re-register
its data with the satellites.
8. Then turn it off and on, and it should be working.

hope this helps someone-

Can you upload georeferenced images and use them as maps or do you need them to be in the Garmin format?

yes you can as long as the image has been correctly geo-referenced, it will appear:thumbup1:

Hi Bertrand,

Montana and mount on order but will be a couple of weeks. In the mean-time, can you tell me what spacings the the 4 holes of that mount are please?

See what sort of mounting I can come up withbier
