i have just installed a new alpine head unit in my R33 s2. the head unit works alright, but the clock on the dash seems to be resetting itself every time when i start my car. even my head unit pushes the cd out and is in off-mode every time i restart my car. the previous head unit was also an alpine. did i do something wrong with the installation? help needed.

I'm guessing there is a "memory wire" (+) that should connect straight to the battery and not via the ignition...

usually yellow wire

i bet you connected memory (yellow) to power (red )

what headunit you have?

i had an alpine unit previously. so i bought a new alpine unit and connected the exact same wires to the new unit. yellow to yellow, etc. what should i do now?

i know its a late post but im having the same dramas, but i know what the problem is but cant the the bloody fuse for the back up, where is it??? am i missing something, in my car tho everything resets, air con, clock, cd player

pull them till you find a blown one. I can't remember placement in that panel.

i did this like 2 or 3 times, thats y im confused cause i cant find a blown fuse anywhere, i must be missing something, its driving me nuts

Get a cable tester (little sharp point thing with the little light in it) and start going through your dash with the ignition off and find your constant power & ignition power cables and make sure you've wired up the head unit properly.

If it's affecting aircon, stereo & clock, then it would have to be a fuse.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
