Mobile ATSC TV tuner

[dataguy]

Does anyone know of a compact ATSC (digital) TV tuner that will work with the Genesis AUX port?

The ones I have seen look like they wouldn't fit in the center bin and seem to use composite A/V connectors. Example: http://technorati.com/videos/youtube.com/watch?v=EBtOUuRQ6hk

I'm not familiar with the specifications of the AUX port for video. Is there some converter cable that will convert composite?

The Genesis AUX jack is a 4-wire plug:
composite video
2 audio wires (left & right)
ground

I don't remember the order of the wires. But you can buy an Apple iPod cable that splits the AUX connector into 3 RCA style connectors. See http://www.frys.com/product/5091375 for an example; I think this is identical to the one I bought (don't remember the model/part number off hand). For giggles, I brought my Zenith DTT901 ATSC converter box into the garage and used this cable to feed the Genesis. Worked fine - can't drive though since the Zenith was plugged into an AC extension cord. I can also plug my Canon camera into this cable and view pictures/videos from the camera's memory card on the Genesis screen - with sound. Better than the camera's itty-bitty LCD.

Several of those ATSC "coupon elegible" converter boxes use "wall wart" power bricks - many bricks output 12 volts so such converters would probably work fine in a car. Several are advertised as "RV ready" or "boat ready" type of things - i.e. they are designed for car/boat 12volt systems. Wire those directly into the Genesis, or wire them to a cig lighter plug and use the power outlet in the console - no mods to your car that way.

As I said, mine worked fine... in the garage with a simple bow-tie antenna stuck through the sunroof. But in motion it might not work well at all - between signal blockage as you passed buildings, the doppler effect, etc. may render "ATSC on the move" impossible.

Thanks, Mike! That's exactly what I was looking for. Ideally, I'd love to have something that's small enough to fit in the center bin without hardwiring.

TV in motion would require the optical bypass, which is quite pricey, so it's more for parked entertainment.

Found a cheaper source on the cable:

I dug up a page I'd printed from hmaservice.com - some of the factory service manual type of stuff. One page shows the pinout of the Hyundai iPod cable:
* Left audio (tip)
* Right audio (first "ring" contact)
* Composite Video (second "ring" contact)
* ground ("ring" closest to plastic body of cable)

Also, I had printed service info stuff on the Tech package electronics. One thing caught my eye... In the "Component Location" pages (too bad hmaservice.com printouts don't have page numbers... you folks will have to hunt hmaservice.com links a bit, as I will if I ever re-print this stuff to PDF) there is a diagram of the main "head unit" (the CD/DVD changer monster box). The back view shows the various connectors on this thing - lots of wires. Two ten-pin connectors caught my eye:
Connector A: "Front LCD Monitor"
Connector B: "Rear LCD Monitor" <-- Hey - what's this!!!!

Comparing the pinouts, they are IDENTICAL. The only difference is the shape of what appears to be a plastic "key" on the connector body. Somebody adventureous might take the cable from their dash LCD and cut out some plastic... and see what they get when it's plugged into the "Rear LCD Monitor" port. Will the NAV and regular functions still work - and display DVD Video while the tranny isn't in Park? My guess: the rear LCD probably is blank for anything except DVD video.

Also, looking at the various connectors on the head unit... I don't see anything obvious for the transmission "in Park" signal. Connector D is clearly the "multimedia system to car mechanicals" interface though. One wire is "K line" - mean anything to anybody? I haven't gone through the rest of the manuals to find what "K line" comes from/goes to.

Another ten-pin connector is labeled "MTS" - again, mean anything to anybody? It's got the same pinout as the LCD connectors.

A separate box/module of the DIS package is the "Media Unit" which is somewhere in the dash to the right of the LCD. The diagrams aren't very detailed... this box is what "talks to" USB memory sticks and iPods though. It appears this is the box that handles the audio+video from the armrest jack; you could splice into wires going into this box if you put your ATSC TV Tuner inside the dash somewhere.

p.s. the opening pages of the DIS chapter show connections for the "Camera Module (Frt & Rr)" Front camera??? For what? Night vision someday?

Likely for one or more of:

• Camera-based lane departure warning system
• Front parking camera, similar to rear (would love to have this)
• Wide-angle blind spot camera, similar to Nissan/Infiniti All-Around

Good research on the connections!

Here's some information on the video-in-motion bypass: http://genesisowners.com/hyundai-genesis-forum/showthread.php?t=2450
