Hello forum!! I have the Alpine CDE-102 head unit and I hooked up my WD MyBook 500Gb external hdd to it. It's a decent hu but the only problem I have with it is that the USB source is only able to read 100 folders and 100 songs per folder! I know if I were to spend a little bit more money there are other HUs out there that goes beyond 100/100 but I was wondering if there are any head units out there that are capable of reading a multi-partitioned external hdd? Thanks!
