Well i bought mine a few months back and did extensive research although i must say i came across a few variants but not sure i saw one that resembled the RNS-E unit so well. The one i have is modelled on the standard VAG group OEM look so its as you would see in say a Golf/Scirocco or something like that. To be honest, the plastic colours match my car perfectly as do the red led backlights.
I have an additional DVB-T digital tv tuner (bought from supplier) to overcome the analogue TV issue but wish i had got the more powerful tuner as mine is weak. Truth be told it is seriously easy to add one of these to the aux later on (unless you want to use that for something like a reversing camera which i also go with my unit).
The screen on my unit is actually very good. Yes it is full touchscreen although an older capacitive style rather than an iphonesque multi touch jobby. As i say it works well and i can see it ok even with my roof down on a bright day.
None of these chinese units will link to your DIS though i dont think so be advised you will lose that function.
GPS comes complete with maps and good software, no problems there.
Like i say, as with most chinese made electronic products, they often look better than they work or in fact are, but compared with other options on the market and at this price point i thought this was the best route to go down given i am driving an older vehicle that may well cost me plenty in other areas!
I will try and post some images for you later if i get the chance.

Theres a number of videos showing different units with different OS variants. I have seen a few of these now (seems most VAG group european taxis are getting them installed) so they are all often just variations on the same theme.
If you have the dosh, i would point you in the direction of an android powered device:
