Navigation SD card part number

I can answer my own question...it works. I least a Premium AWD in Polymetal Gray with white interior today, put the SD card in and the Navigation came right up. I asked the parts manager about the A suffix and he said that was normal for Mazda with Navigation SD cards. He’s said they change the suffix for slight changes (I’m guessing maybe if they have new maps).

i got it from eBay about a month ago from a seller that quite a few members of a Mazda 3 forum had purchased from. It definitely was worth the $43 gamble for sure!

thanks for the info (have you got the link), I don't know what Mazda US wants for their SD nav card but in Canada they want a staggering $569 for the card - that's insane - how can they justify that!

I’m not sure if it’s ok to post a link, so mods don't hesitate to delete this post. This looks like this seller may only ship within US. I believe the US price is over $400, although I saw some “regular” Mazda online part sellers selling them for around $360 US.

at least that is more reasonable for what it is, just charging ridiculous prices just encourages you not to buy it from Mazda, as there is no way I would pay Mazda prices unless they throw it in on the deal.

A quick update, I updated the maps today to the December, 2019 release. All went as expecte.

Thanks for all the good info. I bought the nav card from the same Ebay seller. It worked great in my 2020 CX-30 Select Package, but I can not update the maps. I installed the required Mazda Tools app on my PC but it does not recognise the SD card. Tried two different PCs and they don't see the card. Fortunately the seller offers 30 day returns so it's going back.

Just in case you’re as bad as I was in reading the instructions in putting the card in your car, make sure the little slide switch on the SD card is not in the locked position. When I first put SD card in my car, I saw the bold “Locked” in the instruction for installing the card in the car and didn’t notice the “don’t”. The navigation worked in the car, put when I tried to update the maps on my PC it came up with a message essentially saying there was a problem.

I then realized my original mistake and moved the switch to the unlocked position and put the SD card in my car. I started up my car and navigation still worked (and my home address was still programmed). I turned off my car and removed the SD card and put it back in my PC with the switch still in the unlocked position (correct) and the card was recognized and I did a backup and then the maps were updated.

Thanks, yes the sd card was unlocked. I also made sure I had driven 60 miles to pair with my car, uninstalled/reinstalled the Mazda Tools app, and turned off virus protection as I saw recommended in one of the forums.

I too found the auction from Mazda 3 site where lots of folks had good luck, and it worked for you... so I'd say it's still worth a shot to someone who was considering trying since the seller accepts returns.

Bought it from the seller, tried multiple times didn’t work for me
Glad that the seller accepts returns

Worked perfectly for me. Picked up a BDGF-66-1 from eBay for $50. Inserted it into the SD Card port in the glove box and BOOM...nav is now working. Since I usually use my phone, this is more a novelty but I got the premium trim so the navigation sends more info to the active drive display (HUD). Now I get speed limits and if I want directions on the HUD then I can use the car's nav instead of the phone nav.

Wouldn't recommend it unless you have the active driving deploy (HUD).

ditto. that is exactly what my intent was as well, hence was fine with spending 50$ (ebay) and not 400$ (dealer), nevertheless will give it another shot.

Thanks for all the info guys. It has been very useful.

I ordered this from ebay:

and I works perfectly on my CX-30 AWD premium trim.

I'm told all these Ebay ones are simply copied onto blank SD cards. None of them are actual OEM Mazda. That could be why some people are having issues with updates or car compatibility.

Impossible. The car requires a genuine card in order to register it

anyone tried these guys yet? They have a few videos on YouTube from this company.

Has anyone in the US with Navigation and HUD been able to view traffic sign recognition (TSR)?

It is my understanding and experience that in the US, you only can see speed limit “signs” in the HUD with the navigation SD card installed and the in formation is only from the data on the card. It‘s clearly is not getting the information from “seeing” speed limit signs on the roadway as many roads in my generally rural area are not showing up any speed limits in the HUD despite the numerous signs clearly visible along the roadside. In other areas the data on the HUD (from the navigation card data) is incorrect, not matching the actual speed limit signs along the road. My understanding is that in some markets the camera(s) are used to identify signs along the road.

The dealer here does not install the Nav card until sold so my test drive was with no SD card installed. Traffic signs showed on HUD.
