Not only might be, but is! It's probably a schottky diode from a switch mode power supply.Might be a ON Semiconductor diode.
Thank you. I was able to find that but I wasn't sure about the part number being right.Go to google, type MBRS360T3 , click shopping tab.
For reverse engineering things like this you have to go to the data sheet, check what the manufacturer says the markings on the device should be, how their logo should look if its there, and the device package size. It can normally take some doing if many manufacturers produce the same device and it is too small to put many characters on it.Thank you. I was able to find that but I wasn't sure about the part number being right.
Yes, diodes do fail, but very seldom for no reason. Excess current is often the cause, excess reverse voltage can also break down a diode. AND I am still wondering what are the symptoms as a result. Does the GPS system share a screen with other parts of the car? On mine the radio, CD player, and GPS all use the same screen. Do other parts of the system function???Diodes do fail on occasion, but test the part that you removed to be sure it's bad. Most multi-meters have a diode test function. If it is still good then the real problem is something else.
The diode does not look like it had a 25 amp failure, which usually results in melting and cracking. So presently the GPS does not function. Does everything else function? Radio and other entertainment things?The car belongs to a friend and he bought it with with this problem. I did notice that someone replaced the 10 amp fuse with a 25 amp. It's hard to tell what the previous owners did to it.
So the problem seems to be only with the GPS system? Does it appear to be totally dead? or just partly compromised?Everything appears to be functioning correctly.
If the part failed there must be a reason, some other part failed and caused the part to fail. So of course, replacing that part did not solve the problem.

Not trying to start an argument with you or anything just something you can think about. In automotive modules (which this is) its actually fairly common for certain diodes to fail from external sources and not effect anything else in the module. Many cases it will not have any visible damage to them. Might not be the case in this users situation but its worth keeping in mind for future topics on automotive electronics.The diode does not look like it had a 25 amp failure, which usually results in melting and cracking.
