Thanx for your help

Great product

Great product just got the system so still learning how to use it. I would recommend this to others in this field

Great product

I made the mistake of first buying a Chinese clone Nexiq on eBay and it was nothing but a headache. Then bought a genuine Nexiq USB link 2 and using diesel explorer software it all worked flawlessly straight out the box.

Don’t waste your time / money on the fake Chinese clones, buy the genuine Nexiq adapter
