I have a pioneer AVH P5900DVD that is in my work truck.  I think it cost about $1300 when I purchased it and had it installed.  It's about 6 years old.  
I'm about to replace the work truck and want to know if I should pull this head and install it in my 2001 boxster S or if I should just spend a few hundred dollars and buy a new Pioneer 3800BT which is dual din. 
What I'm wondering is which unit is actually the better head unit.  I have factory 4x40 hayes amp and also have an Alpine 4x75 amp that I could use in the boxster.  
Just needing some advice.  Don't want to "upgrade" to one of the new cheaper units if it's actually not really better.
BTW, I have the 2002 bluetooth module so my unit is fully bluetooth capable.
Thanks for looking.
