Which China/Taiwan 2 Din HU(with GPS) is better?
1)DLAA
2)Titanium
3)I-Max
I know i can go for branded one such as Kenwood and so on but so expensive....

dlaa seems pretty good among the list
though i would recommend skipping the unit with the GPS option and instead with the difference you have saved you can get yourself an entry level garmin GPS which will serve you much better than the built in GPS plus you can carry it around incase you need it for walking![]()
i am not sure how those player will behave after some time of usage...but if looking for something cheap with good quality, do find my thread of epsilon double din. bit more expensive than what you see in the market, but way more stable and faster.
