The issue is, the nav screen isn't working now, at all.
When the key is set to on, the stock DVD for nav spins up, then emits two short beeps. I can remove the maps DVD fine, reinserts fine. I reconnected everything plug wise, remembered the grounding strap on the NAV screen and remembered the large nav plug.


There are two unused white connectors that were used in the stock radio, m39 which I used to tap steering wheel controls (BTW power doesn't work) and one other. Do these need to be utilized or anything?



I triple checked the ribbon cables were still inserted, checked that I didn't accidentally loosen the connections on the DVD drive while taking glove box out, and all plugs (a/C and nav controls, and nav main connector are firmly in place.) I even disconnected (-) battery cable hoping to have it relearn it's peripherals with no luck.



I feel bad because this is my girlfriend's car and it appears to her that I broke it.


Please if you have any info I really would appreciate it. I've searched a lot and the conclusion everyone has when experiencing a dead NAV screen is a bad resistor in the DVD unit or something like that, but I refuse to accept that a hardware failure just coincidentally took place at the exact same time I went and basically rewired the central nervous system of the A/V system in the car. It has always worked 100% until I replaced the stock radio (experiencing dreaded stuck a/c, dead radio symptoms) with a nice Pioneer DD unit.


I would be willing to pay you if we can get this resolved, I just don't like giving her something that's not 100% I've been in the car audio game for a decade and have put in 50k systems, so some POS NAV screen from '03 isn't going to stop me.



I looked at the power diagrams and it doesn't look like anything was interrupted, I can't understand the rest of them well enough to say whether the system was affected or not by removing the stock head unit.

1) I can hear a loud popping noise coming from the speakers but I don't get any sound when playing music/radio, what could be causing this?
2) The HVAC controls still work fine and the HU display works, could it be that the bose amp is toast?
3) Are there any amps that I could just directly swap with the stock bose amp? what specs should I be looking for.

Any help is greatly appreciated!
Cheers

I'm going to try and see if I can replace the capacitors on the amp before I invest hundreds into this.

In case it doesn't work though, what are some amps you'd recommend?

I accidentally purchased the W/ Nav when I don't have navigation.. Will it look any different? I don't mind the extra $30.00 I spent but I'd definitely rather return it if it's going to look any different.

ps: If I bought an AVH-X3800BHS do I HAVE to get a new amp and or speakers?

Not required to add an amp or speakers, but if you had the bose system before, it's highly recommended, since the bose amp is crap. Bose speakers aren't great either.

Do you have a suggestion for a reasonably priced but sufficient amp? I'm already over $600.00 and don't still going to pay for an install. Not looking to get up to a grand if I don't have to haha.

For this reason, I recommend going rockford fosgate unless you're building something for a car show that has to look more impressive than how it sounds at speed. I have JL in my car and wish I'd saved the money... especially since my JL 500/1 that died after 2 months (repaired under warranty) just died again after about 5 years... Rockford Fosgate in the wife's car hasn't had a single issue.

Purchased a PAC-ROEM since I wasn't sure what the PO had used but it looks like a nightmare when I pulled the unit to check what was back there. He had the antenna adaptor connected to some Pioneer component that I can't tell what it did, and a badly wired ASWC-1 that I'll be replacing and cleaning up the butchered hack wiring.

My question is that now that I'm reading through the rest of the post it sounds like maybe I should replace the amp while I'm at it since the stock Bose aren't great, however, if I don't do it now, what extra work should I do this weekend to make replacing it later easier? Also, where is the stock amp in this car?

Edit:

Also, sorry, but if I do go with a new amp like a the Rockford Punch 4ch, is the PAC-ROEM still the right choice for the harness?
