2019 Prius Prime Map Update (7 in screen)

I drive a 2019 Prius Prime with a 7 in screen. While normally I would not want to pay $150–$200, there is a road near me that has been completely redone since the last snapshot of the map in 2018 (fellow Seattleites can probably guess which road I'm talking about), such that the navigation system is near useless. I've seen plenty of discussion on this site about map card updates for the 11.6 in screen, but nothing definitive about the 7 in screen.

According to the Toyota parts website, the proper map card update for my car is the one with the part number 8627135022 (I'd link to the part number, but the site stops me since I'm a brand-new user); however, that card is priced at over $1,000 which I am not paying for a map update under any circumstances. According to the same site, the 2018 Prius Prime, which, from what I can tell, uses the same infotainment system as the 2019 model, can use the map card with the part number 862710E074, which is priced at a much more expected level. My dealer suggested I ask other drivers if they've tried using the latter map card, so I figured I'd ask here. Does anyone have experience using the latter map card in a 2019 Prius Prime (with a 7 in. screen)?

Much thanks in advance for the help.

 

I went ahead and got the map card even though it wasn't listed by Toyota; I can confirm that it installed correctly.
