As I write this review I have been using Lelec GPS for three weeks.  It  has many weaknesses (details below) and one key strength (the maps and  the navigation itself). As I used it I found a way to solve the problem  with the poor screen visibility in the sun which raised my overall  experience to good.  Note: the seller offers two products in this  listing, I am reviewing the one without the rear camera.
As a  background for this review I am a very experienced GPS user.  We  purchased our first GPS in 1999 and between my husband and I had chance  to use a large number GPS units over the last 16 years. How does this  GPS stack up?  It is NOT the best navigation system out there, but it  has several features that I do like.  I hope the pluses and minuses I  describe will help you in your decision of this GPS unit is a good match  for your needs.
The best feature of this GPS unit are the good  maps (provided by TomTom and dated June 2014).  The weakest points are  the user interface, which is uses the old technology for resistive touch  screen and the screen visibility in the sun.  The unit also includes  several very outdated and primitive apps which decrease the overall  impression of the unit, but they are optional so one can just ignore  them.
THINGS I LIKE:
~~~~~~~~~~~~~~
1. The maps are  fairly current (June 2014). The display shows 3-D like rending of the  turns which helps to orient yourself in a complex intersections.
2.  A 7" screen is large and easy to see even for someone with imperfect  vision.  The screen looks washed in the sun, good in the shade, and is  superb during the night.  My video shows the display as we drive under  different conditions.  I found a work around for the poor screen  visibility in the sun by changing where I mount the screen.  Instead of  using the mount that comes with the GPS I mounted it using a Command  hook and "TABI-Stretch it on!" mount over the screen of my car's  built-in GPS.  The maps on the built-in GPS are now out of date and  TomTom maps are significantly better. Mounting GPS in this position puts  the screen in the shade, gives me a great angle and does not block  visibility out of the window (but does block the car's radio as well the  old GPS screen).  At the end of the video I have several shots of how  Lelec GPS is mounted in my car.
3. The navigation system does not  require cell coverage.  Our favorite navigation system at this time is  Google Navigation but it requires cell coverage, which means it does not  work in some rural areas where we like to travel on weekend.  There is  no such restriction using Lelec system. Google navigation has a street  view which allows you to see the actual street and buildings this  feature is not available through TomTom maps used by Lelec.
4.  The speaker is good. It has a good volume level and has a large  selection of male and female voices to choose from.  All of them sound  natural, not like a robot.  I include voice directions in my video with  the volume set to MAX.
5. Destination can be saved to "Favorites".  It is easy to do with just a few keystrokes (my video clip includes an example).
6. You can change units from metric (default) to miles.  By default the GPS is set to metric measures.
THINGS I DO NOT LIKE:
~~~~~~~~~~~~~~~~~~~~
1.  The touch screen uses the old resistive touch technology, where you  need to press the screen very hard. If you are used to touch screens on  the smart phone this type of the touch screen feels unresponsive.
On  the positive side this touch screen user interface is easier to use than  a joystick interface, you can enter destination by typing on the  keyboard keyboard when entering destinations.
2. The screen is  hard to see in the sun.  The image looks very washed out and it is hard  to read labels.  The screen looks much better in the shade or in the  dark.  I was able to solve this by moving the GPS below the dashboard,  but this may not work for some people as it covers the radio.
3. Screen does not rotate, you need to mount one specific way
4. Amazon description says the US maps are current as of 2015. The software says the maps are current as of June 2014.
5.  There an option for traffic notification, however when we ran Google  Navigation and Lelec at the same time Google was generating traffic  warnings and Lelec did not.  The overall result was that Lelec route  took longer than Google route.  In general, Google Navigation  calculations of our arrival time were more accurate over a number of  different trips we did with both GPS doing the routing.
6.  In  the navigation software there is information on how to get updates. When  I went to that web site I had to enter the brand name of the GPS and  Lelec did not match any of the devices for which I could get updates.
To  see the web site where you can get updates: Show map - Destination -  More - Updates and extras.  When I contacted the vendor he told me that  updates can be obtained by calling the Chinese company that manufactured  the GPS. So I am not counting on getting updates.
7. In addition  to the Navigation app this unit has a sreen full of other apps.  All of  them are very primitive and fall short of expectations for anyone who  used similar apps on a smart phone.  I don't plan on using them.
The  strongest feature of this GPS is the map and the navigation.  This is  the most important part of the product, so even though it has a number  of short comings this is a reasonable option for a GPS system if travel  in areas without cell coverage or don't have a cell phone that can do  Google navigation.
