USB Hub
#1
i have a JY-UOS01N4GS unit and i'm using a USB hub on one of the connectors, and my iphone on the other.
with the hub, i have plugged in TPMS, SSD hard drive, DVR, and DAB+, but i'm finding that only one device will work at a time i.e if i use DVR then the DAB will switch off.
is this normal as i asked the question before buying if a USB hub was supported and was told yes.

Sorry, the DVR, TPMS, and DAB+ only can be connected directly to the head unit USB port. because it needs much more power.
Your USB drivers can be controlled and connected by the USB Hub.

if this is the case (which i understand), should you not be informing customers that as there are only 2 USB cables on the head unit, that only 2 devices will work?
therefore if someone plugs in a mobile phone on one USB, the customer then has to choose between using DAB+, TPMS, or DVR.

There are USB-hubs running on 12V, which you can connect to the car 12V. Some of these hubs are able to deliver up to 3.5A.  (almost enough to use a USB microwave Wink ).
Multiple users having devices that draw more power are using this solution. I used it on my previous PX5 as well.
