Hitachi HiSaturn Navi (Sega Saturn)

The Hitachi HiSaturn Navi is a rare, expensive and most importantly interesting, Sega Saturn system from 1995. It was launched about a year after the Saturn launched in Japan and only months after the North American launch.

The feature list was impressive and included, car adaptor, LCD screen, GPS Navigation, Karaoke and more.

When Sega was creating the Saturn system they enlisted the help of several long-time partners - JVC provided the CD mechanism and Hitachi provided the dual SH-2 CPUs. As part of a co-branding or cross-licensing agreement, both of these companies produced their own variants of the Saturn hardware. Both JVC's V-Saturn and Hitachi's HiSaturn were merely coloured variants of the Sega Saturn, with no additional features or capabilities. All three manufacturers, Sega, JVC + Hitachi, released older oval-button systems and newer round-button systems, and none of these are particularly rare, but then Hitachi threw down the gauntlet.

It beggars disbelief to this day. The Saturn was only a year old when Hitachi threw out the Sega mold and released a completely redesigned system jam packed with goodies. It's smaller than your average Saturn - about the same width and length, but almost a third shorter and it's nearly flat on top. It's considerably heavier because of the added components, even considering most of the power supply was made external. In addition to the standard Saturn ports (serial, AV + controller) it has two microphone inputs for karaoke use, a GPS antenna port, video and audio inputs, a TV-tuner port and a line-out port. This was all standard equipment.

The launch price was 150,000 Yen, or about $1480 US Dollars at the time. This certainly helps explain the system's rarity - the price of this system without a screen was more than $1000 above the price of a normal Saturn. Add another 45,000 Yen ($443) for the LCD screen and you've got a system far beyond the reach of most people.

Also accounting for the system's rarity are the production quantities: only two thousand HiSaturn Navi units were produced every month. It's been said but not confirmed that it was in production for only one month, meaning possibly only 2,000 units were produced.

The LCD screen was released at the same time as the system, but only one thousand units per month were produced - half the number of systems. It was a backlit active-matrix TFT screen, a very expensive process at the time, with resolution, clarity and contrast surpassing any other console screen - equal in vibrancy but larger than the Turbo Express. It draws its power from the system, so no additional power supply is required. . It clips to the back of the system and plugs in with a short cable to the 'monitor out' port. When closed it sits flush with the CD door, and has quite a slim profile, when closed the system is approximately the same height as a normal Saturn. The screen is capable of displaying both interlaced and non-interlaced video. It has a sliding volume control, and one speaker, as well as tint + brightness controls and a Front/Rear switch, which serves a very secret purpose (I have no idea what).

A GPS antenna port and a GPS antenna/receiver were standard equipment. In-car navigation systems have been popular in Japan for a very long time, but I'm not sure to whom this particular system seemed a good idea. Installation of the power supply and GPS antenna were semi-permanent, as the former had to be tucked away carefully to avoid unsightly cable dangle, and the latter needed to be clipped to the handbrake. When installed you could use the system like any other navi. The screen showed your location overlaid on a road map, and you could zoom in or out, add locations, plot routes and leave 'bread crumb' trails. No navi software or boot disc was needed, to operate the navi you merely turned the system on with any Naviken compatible map CD in the drive, and the Navi mode started.

Operation was a bit tricky. Unlike normal navi systems the HiSaturn used a controller on a cord, and since two hands were required it was beyond the driver's ability to manipulate the system while driving. In addition, also unlike other navi systems, there was a sensor that needed to be attached to the hand brake cable, and if you weren't parked with the hand brake on there were several functions unavailable to the user, like route planning. Also game playing was prohibited while the car was in motion - without the handbrake sensor installed and the handbrake applied the screen would shut off after a game started to load.

If you happen to own one and dare use it in the car, you can bypass this 'feature' by connecting the sensor cable to anything grounded.

Karaoke was absolutely huge in Japan. To say it was a phenomenon is a gross understatement. Every piece of stereo equipment featured karaoke inputs. Portable CD players had CD+G capability and video output jacks, even the Sega CD system had a karaoke option. With the HiSaturn Navi, the karaoke features were built in, with two microphone ports and independent volume controls, as well as four buttons on top of the unit controlling Echo and Pitch. In addition, there was a control for voice cancellation or multiplexing on the top of the unit. These features are present in other Saturn models, but the buttons are software controlled and only accessible while playing music CDs or CD+Gs.

The slim profile of the system made some extra demands for manufacturing, and because it was released relatively early in the Saturn's lifespan there was no newer, smaller chipset to use. To save space, most of the power supply was made external, but there's still part of it inside. There are two additional PCBs inside, one for the extra sound controls, and one for the GPS. There are many additional chips - video select, audio control, the GPS software, etc. It is fully region moddable like any other Saturn, and you can easily make a switchless mod for playing US or European games without cutting new holes. It has a VCD slot for the movie card, and it uses the same CR2032 battery for backup RAM. There is a cart slot, but the screen cannot be closed with a cart inserted, and the cart will block some of the screen controls.

The system manual makes reference to a'forthcoming' TV tuner along with the never-released hard drive.

Auction Here - It's been quite some time since one of these sold, so I'm excited to see how it does. A regular HiSaturn will fetch around $180.00 and this is much, much rarer. $2,000.00 plus?

  1. Ahhh more slobbering over Retrousbs nutsack. Someone makes and starts selling Star Ocean, not a peep, Bunnyboi does it, SLURP SLURP SLURP.

  2. It will be interesting to see what the Navi sells for. It doesn’t have the LCD screen so I don’t expect a huge frenzy over it, but even without a screen it’s been a while since one has been on eBay.

    It’s such a pity how rare the screen is!

  3. Jake who else is offering SO?
