OBD2 connection issue

i recently purchased a Joying Plug and Play 10.5 Inch Touch Screen unit for my 2007 Jeep Wrangler SKU: JY-JQ115N4G.
I also purchased the joying Mini ELM327 OBD2 reader. there is no connection issue with the head unit and OBD2 reader.

But When i had my car ABS warning light popped up on my car dash, the joying Mini ELM327 OBD2 reader did not pick up any code and i found out i need to get a better OB2 ready as the joying Mini ELM327 OBD2 reader wast compatible with my jscan app either.

so i bought a Vgate iCar Pro Bluetooth 4.0 OBD2 Reader, the problem is i cannot connect it to my Jopying head unit, The head unit can pick it up in the search function but it wont link up, can anyone help?
