Yes it does. This is a micro card however it comes with a SD adapter that will fit into your 421s.

I would check the Garmin website to see if your Garmin will accept the map. But I believe that it will be compatible.

As far as I know, it will not fit, it only fit my old Garmin, even if it fits it does not last long.

Should be fine...standard size I believe. May want to check the specs for your unit on the Garmin site and compare.

This map is for use with the Garmin GPS system. I don't think it will work with yours. Thanks, John

I am not sure I bought it for my Garmin Nuvi 1300 and it works perfectly for that.

I have a Nuvi 2595 LMT. You could go on Garmin's website and check specs. It works great if it fits.

It worked fine on my Garmin Nuvi 505, and I expect it would work fine on your model also.It makes a big difference in performance

Only if you have installed the original NuMaps. It is an upgrade wich did not work on my Garmin. Returned it and got the actual program which worked

Jorge, I do not know if it will work with your GPS, but in my opinion it is not worth bothering with. The maps were worse than the basic default map on my Garmin Oregon 450t. Very few of the towns showed up at all, even the larger ones and the roads were very inaccurate. It was a total waste of money.

The owners manual does NOT indicate the maximum size MicroSD card that will work in this GPS. Online GPS forum discussions mention that 8GB is what Garmin recommends; and a couple of users report that some 16GB cards will work. However, several users report that the 8GB card will hold both US and Canadian maps, with room to spare.

they should have maps available as they are compatible with other Garmin rinos such as the 110 and 130s

Check to see if it has a slot for a scandisk card. The advertising indicates that it does. I use mine for updating the maps. only, so you might want to check with Garmin directly before buying the card.

According to Garmin's site it fits the following: Alpha Astro Dakota 10/20 Etrex 10/20/30 GPSMAP 62/62s/62sc/62st/62stc GPSMAP 64/64s/64st OREGON 450/450t/550/550t/600/ 600t/650/650t Rino 610/650/655t

I would say that this mounting system would fit any Garmin GPS Nuvi model that has the ball socket type. It is well worth the money to find out.

It works for the Nuvi 40, as long as your Garmin has a slot for a Micro SD card it should work.
