After-market retro fit DVD-Navigator for Freelander 2/LR3

[DP007]

Hi! I just bought a Freelander 2 but, since LR doesn't offer navigators with the Costa Rican maps, the cars they sell around here come without the navigator. Thus, I've been trying to find a cool touchscreen to fill up the empty space in my dash. Ideally, I would like something that allows me to watch DVDs, TV, browse my Ipod, connect to the factory radio, and has bluetooth and a Navigator that can be upgraded with local maps. I've seen some really nice jobs in some of the LR formus but I still have been unable to pinpoint specific models that would fit within the limited space available. I would really appreciate it if someone could give me some guidance as to which models would work. Any other ideas or alternatives would also be greatly appreciated!! Thanks a lot!!!
