What is it?

The Lilliput 659 is a 7" touchscreen monitor which uses Surface Acoustic Wave technology for accurate and precise touchscreen operation.

The Verdict:

As beautiful as the display is on the Lilliput 659, it may not be the best bet for every installation. The physical dimensions of the screens bezel and other components means you may very well need more than double din space for adequate installation. If you do have the space needed, the 659 may just be your best bet as its brightness and color saturation is head and shoulders above other factory Lilliput devices to this point.

See the Lilliput 669HB on the mp3Car Store here.



What’s in the box?

As always with Lilliput monitors, everything is included with one minor omission. Connection options include an HDMI to HDMI/USB cable, DVI to HDMI/USB cable, and VGA/Composite cable with sub-connector. Included power options are a 12v cigarette lighter plug and brick-style home power connector. Also included are remote, driver CD, and desk stand. The one omission is the stylus that's typically built into the bezel of the monitor.


Description:

The Car PC market has been fed a steady diet of touchscreen options in the last several months. Not only have the major brands like Lilliput and Xenarc done more with their existing product line, the hobby has seen new companies start to promote new products. Though there are many slight differences on specifications between product lines, when it boils down to it, most devices use the same basic screen technology. In the 659GL, Lilliput has changed the game. The 659 uses a different type of touchscreen technology, creatively named "surface acoustic wave" (SAW). This technology isn't new by any means, but this is the first iteration we've seen in the 7-inch touchscreen genre. Surface acoustic wave touchscreens send ultrasonic waves constantly through the screen surface. When a user presses the screen, the wave is interrupted a touch event is sent to the controller for processing. Science aside, the surface wave technology in the Lilliput 659 allows for precise touchscreen presses, higher light transmission, and a sharper, more saturated image.


Simply put, the image quality on the Lilliput 659 is fantastic. The colors are rich and images are sharp. Though the nit rating remains at 450, the light transmission the SAW touch panel allows makes the screen appear transflective. The glass is still glossy, but its mitigated by the amount of light it passes through. This benefit also allows for a extremely larger viewing radius when compared to resistive touchscreen devices.


Equally as important to the display of the touchscreen is the response, and the Lilliput 659 comes through in this regard too. The SAW touchscreen is harder than the resistive variants, and this results in a surer button press. The Lilliput 659 eliminates the mushiness, giving users greater confidence in a press without needing the eyes fixated on the screen. I did note that it's harder to get a response on the outer 1/4 inch of the screen, but I'm not sure if this is a problem with my test unit or with all of the 659's.

This small problem leads me to a larger gripe I have with the Lilliput 659. The bezel on this device when compared with any other 7" touchscreen available today is huge. Anyone looking to install this in a standard double din enclosure may encounter a problem getting it to fit. I'm not sure if the controller boards inside require the larger bezel, but its definitely something to take note of prior to hacking away at your dashboard. Check out my video comparing the bezel size with a Lilliput 669.



The Positive:

• Huge leap in image quality from the SAW touchscreen
• HDMI, DVI, VGA, and Composite connections available
• Accurate and satisfying touchscreen feedback
• Auto-On still available (via factory menu)

The Negative:

• Bezel size may prohibit double din installation for some
• Missing auto composite switch wire


The Verdict:

As beautiful as the display is on the Lilliput 659, it may not be the best bet for every installation. The physical dimensions of the screens bezel and other components means you may very well need more than double din space for adequate installation. If you do have the space needed, the 659 may just be your best bet as its brightness and color saturation is head and shoulders above other factory Lilliput devices to this point.

I will be doing some traveling soon and be using it to check the status of my car/carPC while parked in the airport parking lot. I've always had this thought of my battery dying on me while the car sits for a couple weeks because of the massive amount of usb devices n such in it. The Connect2Car monitors the vehicles 12v line, allowing me to check it periodically and even start the car to boost it if it gets below 11v.
This would be perfect wfor me when I was single and my car was parked outside, bad neighborhood etc.

Right now it doesnt do anything out of the ordinary for me, that is control the carputer, obd, cameras, dvr, etc.

Now if I had a daughter that could drive...that would be a top priority: security fence, 6 mo driving location history, speeding alarm, panic button, SOS call, tow alert...that's GOLD for parents.
yes its a hardware software combination of sorts. It can be accessed with any internet connected PC via web browser. There is no app for the PC that does it but one could be worked up pretty easily either by sending texts from PC or by using a little php magic. One of the cool things is despite there only being an app for blackberry (for now) i've been able to set up my android device to control it with widgets (via the tasker app). There's also a bit of automation that can be done through tasker. I have my doors auto locking when tasker recognizing me driving 25 mph while connected to my bluetooth device, it auto locks when my car PC goes into standby, and some other advanced stuff having to do with the remote start feature. Apps for android and iPod shouldnt be that far behind though.
