Buy a head unit that has the features you need. Also try to buy one that doesn't light up like the Las Vegas strip. That is much more difficult. Alpine has always sounded bright & forward btw . . . I bought a plain-Jane Dual deck but that was 5 years ago or so. I put the $s into the amps & speakers & a lot of effort into the install & car acoustics. 70 mph top down bliss.
And I can STILL hear the engine . . .
