Aquire operation-installation manual from Mount the antenna on front or side for easy route of coax. Connect red wire to fuse box terminal label ACC or power by ignition. Place power box for best routing of cable to hand unit, under dash, under seat, on left side, etc. Borrow a watt meter to tune SWR of antenna for last step. Happy travels.

Hello Jason,
There should be a little red reset button on the back or the bottom of your unit. Press it in for 10 seconds and see if that will reset your unit.

It is very likely that you haven't got the same CTCSS or DCS codes matched. Try turning them off on both radios.

The squelch control is probably damaged. They aren't very sturdy. Controls on radio's these days don't take a lot of abuse. Luckily, the replacement parts can usually be found on EBAY and aren't expensive but you will have to install it yourself or take it to a shop and have it done if you aren't technically inclined. It's not a difficult job to do but a shop will still probably charge more than the radio is worth to do the repair. If you can find a HAM nearby, you might be in luck.

It's likely that a bulb has died. This isn't an expensive repair although a radio shop probably won't look at it for at least $75. If you are talking about the display being out, that could be expensive. If the radio is old, then the part probably isn't available anymore. It may be possible to fit something else into the display. I am not familiar with this particular radio. The likely problem is a burnt out series resistor or more likely a bad solder joint on the digital display. THAT should be an easy fix.

There is no way to make that radio VHF capable, CB radio's operate in the AM band, and most, if not all VHF radio's operate in the FM band. CB radio's are not capable of VHF frequencies either, VHF is considered around 40MHz and above, CB radio's operate between 26.965 MHz and 27.405MHz that is considered 11 meter band HF. CB radio's are not broadbanded enough to cover anything that far away, expecially the newer radio's, as most of them are controlled via a microcontroller and PLL tuning circuit. the 19DXIV is a great little radio, but will never be able to operate in or even around VHF. sorry.
