pero iniisip ko lang yung benefits nung may separate GPS ako compared sa ngayon na CarPlay na lang gamit ko.

naalala ko din na yung GPS ko noon will show you a photo of the intersection and tell you which road to take

anyway, past is past... just like the CD player, lahat tayo may CarPlay na and the GPS had to go.
FWIW, there are plug-in Android boxes that streams via the Apple Carplay or Android Auto protocol to convert your factory HU into a full-fledged Android device. These boxes have their own GPS and some can even take a SIM card. In other words, these boxes can potentially work independently from your phone.

My old HU used a Garmin nav module that I had purchased separately. Before that, I used a Garmin Nuvi 255w. I got the local Philippine maps from roadguide(dot)ph way back when. I just checked out the site and it appears that the last Contributors' version of the map for Garmin units was released over 3 years ago.

In the context of daily driving, I can see how dedicated nav units with offline maps can be beneficial, but it is evident that the great majority have embraced online/live maps because it just makes the most sense:

1. Nav apps are mostly free and far more capable than legacy nav units
2. Data plans are cheap
3. Internet connectivity and coverage on 4G/5G have greatly improved since the 2G/3G days
