Ok eto na talaga ang final decision, kasi nabili ko na ang unit hehe. I got one of those 5" widescreen Nuvi 1490T. I'm very very happy with it. The map display even looks similar in size already to the Kenwood HU with Garmin module (coz that one doesn't have the map full-screen, it has the info panels on the side of the screen. And being a newly refreshed GUI design, this looks much much neater than the Kenwood Garmin module's GUI. And did I mention ang laki ng screen? Hehe. As a bonus, may Bluetooth sya at malakas ang speakerphone nya (dahil malaki ang unit mismo hehe).

If I had 70K to burn, then I would still consider the Kenwood+Garmin set, if only because it makes a much more streamlined setup, very neat kasi walang power cables running along the dashboard, at integrated solution talaga ang dating kasi hindi redundant yung LCD. But of course, having a separate GPS unit has its advantages, too, like listening to music or watching videos while navigating.

Thanks to oj88 who actually was the first one who enlightened me about Garmin, and also about the Kenwood thing, and how anything Garmin is better than anything AVT. Dati kasi akala ko AVT was the way to go when it comes to Philippine navigation. Btw, I have nothing against AVT, so I hope AVT owners won't hate me.
