how do you rate it's sound quality? i heard it's sexxcelent
as for hidden functions, try this with any pos-2001 alpine heaunit... Holding Power/Source button, quickly press any other button on the head unit, such as Bad/Tel, Mute, play, 1,2,3,4,5,6, etc...
good luck dude, i heard nothing but positive thigns about this hu, except for the motorized faceplate wearing off //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
alright, but test some of these "hidden functions"... im curious to know what 7998 has hidden
just hold Source/Power and quickly press any other button... you can't really crap out anything unless you reset the eprom which will basicly reset all the settings to factory default or use those buttons that makes your volume jumps to 25 in a wink of the eye lol... in this case have the unit paused
well i tried your hidden fuctions slaugh and when i held down the source button i pressed every button i could nothing happend all it did was turn off the unit
