Is it worth buying the 2nd hand Alpine HU from Odeyssey Car? Price about S$350 2DIN. What thing I need to check for 2nd hand unit? I looking for IPOD ready and a shop recommended me to buy the above if i don't want to spend too much. I am using stock HU without any ICe setup yet. I want to listen to IPOD for now and have no intention to upgrade my setup yet. I may prolly upgrade like 6 - 10 mths or a year later.
