1 answer, posted 100s of times 10,million times, world wide.
same as all cars.
1:pull battery neg lug, for 5min, (see radio die and NAV , after)
2: pull all PCM fuses,bam, it forgets
3:connect any scan tool, and press reset
4: correct error and drive them off, (the do clear,but can take like forever on some...)
#1 causes big time havoc on new cars.

WHY, IF A NEW RADIO IS BEEN INSTALLED, JUST PURCHASE A RADIO PIG TAIL FROM THE RADIO PLACE FROM ISUZU TO WHAT EVER SONNY PANASONIC WHAT EVER., IF THE WIRES WERE CUT, FIND THE RED WIRE, POWER KEY ON.
BLACK WIRE GROUND.
YELLOW WIRE POWER WHEN LIGHTS ARE ON.
BLUE WIRE POWER ANTENNA
THE REST IS EASY, YOU CAN MATCH COLORS LIKE GRAY WIRE AND GRAY WITH A TRACE OF BLACK.
GREEN WIRE AND A GREEN WITH A TRACE, YOU GET WHAT I'M SAYING RIGHT, IF YOU NEED TO KNOW MORE SPECIFIC LIKE R/F L/R L/F THEN GET A (AA OR AAA) BATTERY AND TOUCH WITH THE WIRES BOTH POLARITY'S YOU WELL HEAR THE SPEAKER MAKE SOME NOISE, THAT WAY YOU KNOW WERE THEY ARE LOCATED. BAT FIND THE POWERS AND GROUNDS FIRST.

Look in your owners manual

The stock radio has two electrical plugs and the anneena wire plugs in and theirs a grond wire that goes on the back of the unit with a bolted connection. If you have an aftermarket radio you can get universal connectors at major dept stores that fit your car ( or auto parts stores) These connectors plug into the cars wire harness and the wires are labled to what they do and just connect the wires as marked on the sticker on the radio. If the radio is a factory radio that did'nt come in an Isuzu their commonly not marked and the wire pattern in the back of the radio has to be figured out.

id say the radio is gone ,,,it must also be connected directly to the battery thats why its staying on,, you can get a second hand one in a breakers yard for cheap,,hope that helps
