Pioneer experts- Needing advice, is newer really better?

[chaiyz]

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.
