One of my goals (mad, evil plans?) is to get my Xbox 360 working in my Tahoe. I've figured out some of the details. I figured I'd document them as I go in case anyone else is as crazy as I am. I'm also very interested in feedback or suggestions! Wireless Internet: This part is pretty easy, albeit expensive for service. Fortunately I have a card and router from work already. Sprint Nextel Wireless Broadband PC Card - $110, $60/mo. Linksys WRT54G3G-ST Wireless Broadband Router - $250 DC Power Cord for Router - $10 I'm just going to mount it with velcro in the back, since there's a 12v jack there. Display: The built-in overhead entertainment system in the Tahoe has AV RCA jacks. The quality on that is going to be pretty poor, though. I'd love to know if I can hack into the LCD directly with VGA or Component instead. I don't know if the wires even exist for that though. Another option if I want to go bigger (and HD!) is the Hori Compact HD TFT Monitor EX - $400. Adding a display exacerbates the power issues (see below) and cost. I'll probably stick with the overhead screen unless it's very hard to read or play. Xbox 360 System: If I do this semi-permanently, I expect I'll pick up this 360 deal - $200 and trade back in the wired controller. I have an extra 20G HDD for the 360 already as well as component cables. Since I'm only using A/V jacks, though, I'd actually prefer the more basic RCA-only cable included in that deal to save on clutter. Xbox 360 Power: Power is another issue. I originally thought of going DC-to-DC to save on heat and the size of the inverter. The Big Cat Tech Xbox 360 specific DC-DC option - $200 is from a UK-only company who didn't respond to emails. Another option I investigated is the OPUS 250W DC PSU - $200 and put it in a Project box - $10 with the proper cables if necessary. Either way I'd need a cheap 360 PSU - $40 to hack up (if I didn't want to destroy the one that came with the system above). Instead of DC I ended up ordering a DC-AC power inverter. It's easier to get and more versatile since I can power other things when the 360 isn't in use. Unfortunately the 360 needs a true sine wave inverter capable of at least 200W (for those who don't know, true sine wave inverters cost a lot more). My 07 Tahoe Owner's Manual states a maximum of 20A at 12v, or 240W. I found the Samlex 300W Pure Sine Wave Power Inverter - $160, which will hopefully work fine. I didn't want to have to go to the battery so I like this model. Worst case I can still install it more permanently and wire to the battery. Xbox 360 Mounting: Semi-permanently mounting the 360 will prove to be a challenge. I have the 2nd row buckets rather than the bench seating in my Tahoe, so I can always stick the 360 there temporarily. I like that access to the back, though, so I want to get the system under the seats. The fronts are full of wiring thanks to the 12-way power seats unfortunately. I may be able to cram the 360 power brick and the DC-AC power inverter under them, though. Not sure where the 360 will end up though. Estimated total: $730 and $60 a month While not complete, I've got most of the pieces in place already. I'd love to hear suggestions or comments!
