Thanks for the response- Yes, there is a bar on the left side of the screen and it is scanning thru some numbers- 18,9,43,16 ect. I have had it show quite a few bars on the bottom of the screen but only 1 or 2 of them have had any gray area in them. And it hasn't given me a fix at all. Please excuse the terminology as I'm still learning about this new technology and haven't caught on yet.
I'll take it to work today and try putting it on the hood and see what happens. I bought the unit from Page Computers and they seem to have a pretty good return policy but I just don't want to go thru the hassle. Especially if I'm the dummy and not the unit!!
Thanks again for the reply
