I have worked it out!!!

this is NOT a DIY task. I spoke to clarion USA this morning and grabbed a service manual for a PN-2615 for note taking and comparision to a 2413E /2414E (one is the bose version one is the plain one.)

bear in mind I have BOTH service manuals here to compare with.

two major things differ. Main Processor ( this sets the FM scaling I'm lead to believe) and Radio front end.

for the 2413E the radio front end is setup in this fashion

AM - 522-1620 Khz - 9Khz steps

FM 76.0-90.0 Mhz 100Khz steps

for the 2615E its setup this way:

AM -520-1710Khz 10 Khz steps

FM 87.6-107.9 Mhz 200Khz steps

the processor controls tuning voltage and PLL functions.

externally across the PN-2413E and the PN-2615E they have the same chassis apart from the CD changer. the 2615E changer pinout is 180 deg OUT of sequence with the changer used with the 2413E. that means a full board swap is out of the question.

that leaves a FULL unit swap in which case those WITHOUT the OE Navi option can do it. processor on the USDM unit will run everything. the KEY difference between your radio and the NAVI version is the 8 PIN AUX IN . Cars with out Navi do not use this option. so to fix yours you need a PN-2615E or the COMPLETE ASSEMBLY off ebay.

for those WITH OE navi the process differs. it will require a FM Front END swap and a Processor swap.

currently I'm looking at the USDM items as this is what I have to work with. once Clarion Oz reopens I'm going to look at LOCAL units for a LOCAL processor so you get the correct FM/AM bands

Locally the RADIO front end is setup in this fashion:

FM 87.7-107.9 50Khz steps*

AM-522-1629 9Khz steps

*(you see it as 100Khz. the audio is set up as 30hz-15Khz with the stereo carrier at 19khz. the rest is a guard band)

so if anyone knows where I can find a 350z radio or 2004 Pathfinder radio then I'm ALL ears. and I'm not fussed on the audio side of it (IE bose or not.) as I need the model number of these units so I can compare notes. ideally I would like a chassis to compare against the PN-2413E I have here.

balls in your court now :O

Looks like more mods to do!

My wife's been complaining how 'fuzzy' the radio is... having 101.1 FM & 101.9 Fox stations converted on 81.1 & 81.9 positions, combined with 91.5 Vega in the middle at 81.5 position, 3 stations so closely together is not very good. Vega comes out best (91.5 Mhz on 81.5 position), with the other 2 rather fuzzy or 'ghosting' effect...

Rianto,

yep.

These things will have to be on an exchange basis. it is NOT something I can do on a trip out of town as I NEED my workbench to do them. (sorry victor :domokun: )

for those with 70th aniv. cars these run a DIFFERENT radio ( they run a PN-2615E) the ones I mod currently are PN 2413E.

if someone has a PN-2615 they have pulled out - I'm all ears.

later cars (IE 2004.5 + ) no rework yet. I cannot find a unit that will keep the MD working.

  • 1 month later...

processor swapped out - 100pin ASIC = absolute PAIN IN THE ARSE to remove. putting it back on - easy. no tuner yet (still waiting) so I can't fire the unit up without it having a heart attack.

  • 3 months later...

update:

still trialing the 2413/14 twins.

The 2004 spec radio (PN2613) has been sussed out. I found a processor that will run with it. going to take a bit of fiddling but its definitely doable!!

experiments start once I get the processor here.

need to start on the 2005 version properly now. I'm going nutty looking at 4 schematics/ 2 chassis's at the same time.

Jon Chan,

expect a call on the white car in about a week. yours was one chassis I've modded, no stacker for it -YET.

I did a non bose one first up. the bose version gets donethis week in the same fashion as the other. I'll test mule it for a bit before I go further. short version - it works but needs tweaking so that the whole sytem works as its meant to. currently I run the non bose one without the stacker attached.( I keep selling the stacker thats meant for it!)

only issue with you lot is going to be cost. I'm doing these simply because I was told I couldn't. for a fully reworked (radio and CD) its NOT going to be cheap.

radio only will be a LOT more than the cost of an expander but it will give a fraction of the issues.

put plainly I spend the best part of 6 months on this and I'm not letting it go for nix.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
