I have a 2016 Mazda 6 sport. It does not come with navigation but there is an SD car slot. Dealer wants $399 or $499 (installed) for it. On Amazon these are being sold for $280.
Any advice or suggestions on how I might bgo about getting an SD card and getting it installed for less?
I have not been on the forum and not explored it. I am sure it has been discussed before. I apologize.
This question does seem to come up every few weeks. I agree the cards are ridiculously expensive for how rarely they seem to actually
update the maps. I bought my car in August 2015. The SD card had maps from April 2014. IIRC, the first map updates weren't available until late November 2015. The maps were supposed to update every 6 months, not every 18 months.
As far as installing it, you plug the SD card into the slot, and that's pretty much it. Don't force the card. If it doesn't slide most of the way in easily, flip it over. Once it drops into the slot, you'll need to push down a small way to engage the spring-loaded lock. To remove the card, simply push down to release the spring-loaded lock.
As to purchasing a card, be very cautious about third party sellers, and especially wary of anyone selling used cards. After 60 miles, the SD card locks to the VIN of the car. Without hacking the card, I could not give you my card because it wouldn't work in your car - VIN mismatch.
After the card is locked to your VIN, the free mazda toolbox software should let you update the maps. I don't know how it will behave with 3rd party-purchased cards, because I've never tried.
