Good morning dear Mr. Alexander , thanks for your information
Both of them has the same funtion, their difference is :
this device SP239 vxiag vcx nano for ford/mazda the hardware is made in China by ourself
device SP177 is facory hardware and we made it( means the sp177 not original version)
And also SP239 now can support V96 version if you have
Hope it would help you.
In such hot season,please remember drink more water,and also need take care of yourself,
if wanna go out , need prepare the heatstroke prevention.
At night for sleep, if open the air conditioner , need tuck in the quilt,in case of a cold
Best wishes
