Dear Gentlemen,

Almost 3 weeks old palang ang unit ko.(Everest 2012 Ltd 4x2), I am looking for the following accesorries;
1. GPS including Monitors @ 2nd and third row.
2. Amplified Sound System capability to drive subwoofer etc. (Dedicated for unit-Music Lover ang owner)

I do hope to have a good deal for one stop shop / considering the ideal price fit for my budget. To all pioneer forumers, thanks for your advice ang comments.
