Very many - too many - restrictions of the Lexus RX 400h

According to product specification, this extension offers full compatibility with the Lexus RX 400h. Well, that seemed to considering the amount of an exaggerated promise, so I had not at all expected. Nevertheless, there were too many compromises with which I will briefly describe:

(1) No display of titles, songs or numbers on the TFT display, rudimentary and incomplete - ultimately only arbitrary numbers - on the small radio display (you could even live with a pinch)
(2) a majority of the tracks can not be played in the USB mode, regardless of how to build the folder structure. Here I proceeded in my experiments both creative and meticulously according to the instructions - you end up almost in an endless loop of the same old few folders that other songs were not accessible. Advantage is taken not to some extent the USB potential. Therefore you would have to 5-10 for folder - with folders I mean only the headline of an album as soon as one is more about folders, for example, "Classic" creates the device overburdened - each set a different USB flash drive and then replace them, whereby the whole thing is absurd, because then you might as well use the built-changer, an MP3-CD has a similar capacity.
(3) if you have plugged in a USB flash drive, you can not switch to streaming via Bluetooth. One has to take the USB stick in order to stream can always first. The Bluetooth streaming songs went so far, so good, but control only the mobile phone possible.

I was referring primarily to the USB function, the associated restrictions set for me is a no-go, especially the item (2) above. Who wants to just Bluetooth streaming, which is adequately served. Rescission by Zemex was a bit tough, but easily squandered installation and removal time about 2h.
Property me now a Vaistech USB device retrieved - cost nearly three times only for USB, but is a completely different number. Already alone execution - metal housing and many times more weight, clean software integration into existing sound and navigation system, title display, cables neatly laid in cable hose, etc. etc.
Has once again confirmed an old truth - you get what you pay.
