HTC Diamond is supposed to be revealed at a press event this upcoming Tuesday but some images and the specs have already been leaked to the media somehow. Here is the latest:

Becker Traffic Assist 7977 was unveiled couple of months ago but it wasn’t until recently that it appeared on their own website. The new Traffic Assist 7977 is their top of the line GPS navigation system with a 4.3″ touch screen display, live traffic information, lane assistance, and maps for all of Europe.

Nolan is a new bluetooth GPS receiver that made an appearance on Semsons recently. There’s nothing too special about this bluetooth GPS receiver except the good price which is currently going for $43. The specs are pretty standard. SiRF Star III GPS receiver capable of 20 channel satellite tracking, Bluetooth V2.0 + EDR transceiver, and battery that can last up to 10 hours.

Garmin’s nuviphone is coming pretty soon and we have some more details for you. An engadget reader was subject to a Garmin survey which looked like in the pic. Although not in the image, this reader was asked if he/she would purchase the device from AT&T with a 2 year contract… the $20/month being on top of a regular voice plan.

Altina just announced a new GPS navigation system for the Chinese market called A850 3D. As you can tell from the name it can render almost realistic images of roads; complete with buildings in 3D and can split the screen in half to also display a traditional 2D map.

JVC recently added the 7-inch, double-din KW-NX7000 Navigation/DVD/CD Receiver to its 2008 line-up. The unit’s faceplate is detachable and features a 7-inch low-reflection touch screen monitor. Also included in KW-NX7000 is a proximity sensor which illuminates the relevant keys when your hand approaches such as during navigation, DVD and movie playback to reduce distraction. Also now there’s a built-in memory so you can use other multimedia sources and navigate simultaneously.

TomTom just made the availability of the new TomTom GO 930 and GO 730 official for North America. The main difference between the 930 and 730 is that 930 offers maps of United States, Canada and Europe, whereas 730 only has United States and Canada installed on its internal memory.
