-picture quality and brightness (too bright?)
-compability to USB thumbdrive or Ipod
-Garmin GPS signal and update issues?
-how long have you had the unit?
-ease of use, general quality etc..
Would appreciate advice or problems you encounter before or after you installed the unit. Of course good comments will make me make my decisions easier..
No offence to sellers cos I had been looking all over for reviews but to no avail.
Cheers..

I will try to answer your question. based on my experience testing it...
Sound quality.- not bad. i test a unit before this (for about a week)... the sound is clear for radio, mp3, sd card and dvd. did not test GPS (did not have on my unit) and tv (did not have the antenna)
- sub woofer rca out really good ... compared to my jvc unit which only had 1 channel out so have to split between front speaker and subwoofer.
picture quality and brightness- in normal daylight .. the default setting is ok.
- at night, might want to tune down the brightness a bit (can set the brightness in setup menu)
compatibility to usd and/or ipod- usb if not mistaken up to 8gb. but did not test, i only have 2 gb in hand. no problem with 2 gb thumbdrive. (same goes to sd card - only test with 2gb sd card)
- external hdd is not supported ...
- ipod port is only for IPOD. Iphone not supported, only ipod. did not try as dont have ipod, but warehouse ppl inform me this.
- one more ... not all DVD is readable ... some dvd that is quite transparent (like some pirate dvd) cant be read by this player. ori dvd no probs
garmin gps signal and updates- signal ... got antenna .. for better reception .. stick @ roof (magnetic) .. but up to u or the installer where to put it
- updates ... well ... map updates ? malsingmap is free right ? did not test it as my unit do not have gps
how long had the unit- 1 week.
ease of use, general quality- simple enough to use.
- setup is also simple... though i prefer to be more complex so can set many things
- buttons could be a little bit better ... but usable lah.
- touchscreen is ok, responsive.
- touchscreen can be calibrated back in the setup menu.
i add one more:
ease of installation- not that easy if you dont know how or dont have any experience
- lack of manual should u want to DIY install
- if bring to shop that dont have experience installing this kind of player, they might need to test first, so will take a bit longer time to install.
thats it i guess ...
