This a problem between my 1998 Chevy Blazer 4X4 & a Verizon HUM.
I bought the HUM to track some diagnostic issues and a few other things. It works great, when it works. However, the HUM that I attach to my blazer
After 2 to 10 months, they die. I have no idea what is causing this problem. On the HUM website, it says that it's fully compatible with the 1998 Chevy blazer 4X4.
So why do these HUMs keep dying?
Does anyone else have any problems with Verizon products and their vehicles?

 

Sounds like this "HUM" device is just cheaply made...

Hell I've had a $5 ELM 327 bluetooth OBDII adapter hanging from my ODB port for over 3 years and it has never failed me...

 

I agree that it's very cheaply made. I'm on my 5th or 6th one now. I just want it to work.
It's does a lot more than just bluetooth, though. It also does GPS, builds up a wireless network wherever me and my truck go. It is also a device that can detect crashes, you can use it to call for help, or just but the HUM customer service people because it stops working.
Anyway, eventually, it stops doing everything.
Mainly, I use it for my grandchildren. They all have their own devices and connect them all to the truck wifi (no data limit).
For $10/mo, you just can't beat it. For now. :-)
Thanks for your input though.
