my simple review on the Multimedia Display + GPS
1) Radio functions great. allows you to set total of 12 channel (FM1 + FM2 6 each), so my SA set it FM1 to all eng channel & FM2 to all chinese channel
2) USB Song player : Cannot display korean words. so far can read eng, chinese & japanese. didn't try others.
3) USB Song player : It wont remember your play mode (repeat all, repeat folder, random etc). I love to random all songs in the usb but once switch from repeat to random, it goes to next song.
4) USB Song player : If you group your songs in folder, the player display them in folder too. I believe this is nicely done unlike those without display, you can't really choose which song
5) GPS sucks. Allow you to choose routing method but end up all 4 method gives you the same route 95% of the time. Only give you one route, unable to choose from multiple.
The only way to switch to other route is if you know the first portion of your "another" route, then force gps to re-route since u didn't follow its first suggestion.
6) Sound setting is considered good. got equalizer & can configure bass, middle & treble level. nice if you came across a song u want to enjoy in strong bass or strong treble.
thats all for now, will add in if discover more
