I need help in choosing a head unit. I am having my system hooked up but my head unit which i ordered a Pioneer Avic-n1 is as they claim difficult to find. so for the time being they replaced it with an eclipse avn2454 but i know nothing about this unit. if anyone could please help with some insight. my intire system consists of: 2004 ford f150Pioneer Avic-n1 VS Eclipse Avn2454
3- 13.5w7
3- sets of JL audio components csi 650
3- v12 1000 watt alpine amps
1- v12 540 alpine 4 channel
4- farad capasitors
1- optima battery
4- monitors through out
Now the last thing is the head unit which is the most important but the only two that I research was Alpine Iva9001 or pioneer avic-n1.
