Will this NAV Unit Work in my 4Runner?

[BinaryMan]

I have a 2003 4Runner limited with JBL/RDS system. I am planning to upgrade the HU to a NAV HU. I'm looking at a E7007 on eBay wanted to know if this HU will work with my 4Runner or if I need to make modification. Here is the link to the HU I'm looking at:

TOYOTA FACTORY NAVIGATION W/REAR ENTERTAINMENT : eBay Motors (item 300402243167 end time Mar-08-10 09:31:42 PST)


Your assistance is appreciated.

Thank you.
