Personally, I don't trust Chinese made gadgetry. It's lightyears away from the levels of Japanese or German made equipment. Every MP3 player / knock off iPod adaptor I've bought from a Chinese manufacturer is unsuable or is so poorly designed, that it causes more frustration than anything else.
They're selling that gizmo purely on spec and price, which should never be the sole reason to buy something. I suspect quality and unsability is severely lacking. Who watches TV in a car anyway?
I suspect you are entirely correct. However, in the meantime, I see no harm in further research. There is potential for it to be decent - not as much as the potential for it to be a pile of steaming rubbish, I admit. But the chance is there.
IF its half decent, it offers a considerably better interface and featureset than the BMW system. The BMW system is a decade old (Mk4 is slightly newer but did not massively change the interface) now and looks and feels like a 10 year old IT system. Because it is. Now this wouldnt be a problem if its price reflected this but it doesnt, it's still eye wateringly expensive to retrofit.
Rather than this unit being cheap I think the alternative units are expensive. Lets look at how much this sort of functionality costs - a bluetooth module for your PC is £5 retail. A digital TV tuner is 20 quid retail. Just because we've come to accept the fact that BMW charge £300 for Bluetooth and £600 for a dealer digital TV module doesnt mean this is how much its actually costing to make!
It's like suggesting a 1Tb hard drive for £65 is a cheap knockoff because a Microsoft Xbox 60gb HDD costs £59.99....
And once you've retrofitted it, you've got no touch screen etc etc.
However, until now its the only real choice if you dont want your interior looking completely crud.
I'm just interested to see how these fare, thats all
It's also not a great place to have a sat nav screen - not anywhere close your natural line of vision when driving.
It's the same location as the OEM nav screen.
