This Papago R5800 (RM899) device goes head to head with top end Garmin Nuvi 765 (RM1299) on features. It has junction views. It has lane assist. And it has the main advantage that Garmin devices held so long in Malaysia/Singapore, that is free regularly updated maps from local mapping community such as Malfreemaps.
I had a “wait-n-see” stand on R5800 all this while. But after this whole hearted endorsement for Papago maps/devices by Antyong, I’ve moved that stand to “buy-with-spare-fund”.
