This is an unfinished hardware unit with non working software. Do not buy this garbage. I bought this unit from Sheng Jay automation through Alva Tsung paying $360.00 for one unit. It’s software hangs every few seconds. The Video does not render properly and hense the map is a hazy mess. The USB port is not functional. It is just ornamental as was told to me by Sheng Jay. Hence you cannot update the OS / Windows software. No drivers are available for MP3s or Video formats. Video cannot refresh. Audio is one of the worst examples of what can be wrong in designing the hardware.

This ugly schtick is too heavy and cannot be carried in hand. This unit does not mount on the car dashboard. The GPS antenna does not work. USA Maps are not available with the unit. This unit comes without any Flash SD cards and you have to buy these cards and a card reader from a hardware vendor like BestBuy or on Ebay.

By the way you should also pay additionally for the Maps software and take all pains to burn the maps to the SD Card. The SD Card slot has a limitation of 1GB and hence you cannot put all US maps on one card. So you have to buy multiple cards and use them based on where your car is at that moment.

There are hundreds of other problems I have seen, which are too many to list here.

There is no John Stead in real life and blood. John Stead is Sheng Jay
Let me explain what is not working in detail:

1) USB Port: The USB Port is not ”broken”. It just does not exist inside as an installed hardware component. The USB Cable that comes with it and the USB interface hole on the device is just a dummy, a sham. If you connect the USB
Cable between the PC and the device, nothing happens. This was already confirmed to me by Alva Tsung, who is selling these units all over the world, including mine.

Because there is no port to communicate with your PC, there is no way to update your software on this unit, including the Operating System.

2)Software Hangs: When u try to navigate between the menus or within the menu list and press a ”Back” or other option, the unit simply hangs and does not respond. This is not a Windows problem. This is the bad GPS Application software written on this unit. If You press any of the keys more than once, it freaks out and restarts the GPS unit, thereby losing all your work.

3)Video Problem - The map Image gets garbled once you are moving from one part to another, not something I have seen on other GPS Units. May be the Processor is too slow or not fit for this bulky unit or something. The Hardware, OS Software and the application software are just not blending well and hence this unit is a complete disaster.

4)Audio problem - The Audio Prompts are too low in volume and not audible when you are driving. The audio quality is poor and gives a whirrrrr kinda noise rather than clear prompts.

5) Maps - Not included in the price. You have to pay additional charges to buy any maps you want, be it US maps or Canada maps or EU maps. You have to buy them and burn to an SD Card or compact Flash card - Your Penalty is $50.00

6)No SIM/SD cards included - This unit comes with no SD or Compact Flash cards. You have to buy them additionally and when you buy the map software, you have to burn them to the cards and use them - Your Penalty is $20.00 for a 1GB SD card.

7) No direct copy of the Maps to the Unit - The Unit does not support any storage, other than the existing and non-upgradable OS. This means, you have to buy an SD Card Reader/Writer and write your maps to suc additional hardware and use them in the SD card slot or the CF Card slot provided on the unit - Your Penalty is $30.00 to buy the card reader/writer.

There are several other problems which are too many to list here like Non-working menus, menus disappearing while using, keyboard view disappearing while using, not being able to input any address in straight address format, etc.etc

Please be aware of these problems, before you invest in this unit.

Thanks for this post. I thought so that this GPS sucks. Probably I will just buy an engine performance chips and let myself know the way.
