Maps on memory card

Hy, their's no problem with this, just insert your SD card in the slot of your GPS and get it on that's it in Australia you'll see the road and all the poi's.
Salut Clem.

Normally it'll just work as the maps don't overlap, as that can cause issues. However I'm not sure how large the Aus & NZ map is, as I believe your nuvi cannot handle maps larger than 2Gb. I suspect it's less so should work fine but check with Garmin first if no one here knows.

Considering the age of the 350, IMO, you would be better off buying a used or refurbished newer device with these maps pre-installed. If you can find one, it may not cost much more than the add-on map, and you will get much better functionality with a newer device.

For example: https://www.ebay.com/itm/Bundle-Garmin-Nuvi-52LM-2019-Austra...

Insert the SD Card. Turn on your Nuvi 350 and check settings - Map to make sure it is recognized and selected.

My first GPS was a NUVI350 and guided me well for several years.

I upgraded to a NUVI2555LMT a few years ago and it was well worth the expense. I would seriously look into getting a newer model, for several reasons.

350 only allows one via point. Newer units allow significantly more via points. This easily allows you to put in enough via points to insert all the via points you need for your whole trip.

350 has a tiny display compared to available units now. For me the 2555 us as large as I need, but you can go larger if you want.

350 does not allow custom avoidances. I have set up a number if custom avoidances, that have been very helpful, both on a permanent basis, or temporary use, such as long construction detours.

350 does not have lane assist, that shows a display of your exit ramps, with guidance to show which lane to use.

350 dashboard is very limited. I set my 2555 to display ETA to final destination, Time to next via point, elevation, & speed. I expect newer units allow this flexibility and my setup is what works for me. You might want a different setup.

350 does not display speed limits. Newer units do and might save you a speeding ticket.

There are many advantages to new units and the cost is a drop in the bucket to the overall cost of your trip and might make your travels much easier. If you do replace do it sooner than later so you have time to get used to it in familiar territory.

Good info. Thanks all!

@MikeSid … Out of curiosity, did you decide to go ahead with the map card for your nuvi 350? If so, did you encounter any problems?

But will likely get the map card. Will report back.

Thanks for posting this thread.

Just copy the files to the card.

this is practical advice.
