    Alright, guys and gals. A question for you CB wizards out there. Purchased a new CB and mirror mounted antenna for the truck, as we all know these internal factory antennas on the Cascadias are about worthless. The day after I installed everything I started getting a No GPS Signal on my Rand McNally GPS. It would freeze up for awhile and then reaquire the signal. Did this regularly throughout the day. Thought maybe the GPS was taking a dump so I bought a new one.

    Same model GPS as the old one, and after putting it on the windshield, it started doing the same thing. Started thinking it could be the coax I installed so I switched my CB back to the factory installed coax.

    Am I looking at a coax issue or an antenna ground issue here? Any help would be appreciated. Thanks!

    What gps is it..The gps may need updateing...
    I know most rand mcnally gps units would work fine 1 min then freeze up..I had a cpl 500 modeled and they worked fine when they worked ut when they freeze up i had to shut off and restart..
    Other than that cb shouldnt affect gps..If anything the charger puts out a good bit of atray rf noise in a radio..Then again hid and led lights do the same..

    It's the TND 530. Did everything Rand McNally tech support told me to. Rebooted with the little reset button in the back while holding the GPS outside the truck and away from buildings. So far, after switching back to the factory coax, I haven't noticed any loss of signal on the GPS.

    Odd...Dont see how it affects it but seems it did..
    Be aware that chances are that gps will freeze up every so often..Unless you get a fluke one just lettin ya know..
    I have a 2 530's a 525 and 500 i think..All did the same and rm cant seem to solve the issue...
    I found a deal on the tnd tablet and bought..ZERO issues..
    If you end up haven to get another go the tablet or a garman diesel..
    Dont bother with any of the 530 series or 700 s in rm..

    Yea, not real happy with any of the Rand McNally products. I buy them because I'm familiar with using them. May just switch brands. I've heard good things about the Garmin Dezl.

    Only thing I've ever had that jammed a GPS signal was a PeopleNet unit. I put a switch on the power wire so I could turn it off when I wanted to use the GPS.
