Added double din nav/media player, bt/streaming with backup camera. Original speakers/sub were already messed up so I added 8" kicker sub in original location with cheap boss amp. I can proudly say I do not miss new car tech because I got them all for under $400

I hacked some. As you see the first photo, I added a latest navi to my 98 Celsior remaining the factory original since I needed it to control the A/C and the audio sources as well as the back up and front cameras. One another reason was to use the factory original amp and the sub woofer.

I also needed to connect an external MP3 player or a cellphone. To achieve this, I analysed and hacked the board under the original navi unit and found the ports which can accept the non-differential signals. You need to use a soldering iron but it's an often case when hacking.

The second photo shows the pins for L and R inputs. Now I can listen to external audio sounds through these 2 pins with 2 attenuators 12dB each. Without these, the sound level was a bit too high and slightly distorted. The factory sub woofer works perfectly.

My AUX mod to the CD changer harness, a Bluetooth car AUX receiver that allows me to wirelessly stream music/nav as well as take calls through the car's speakers, and a mount for the above.

Eventually I plan on going to a double din unit but frankly nothing out there impresses enough, though hopefully the tablet style Android Auto headunits that will start hitting the market this year will change that.

Other than that, a good radar detector and maybe a HUD setup are the only "modernization" mods I would consider.

these cars have surprisingly good sounding factory systems. even the early ones. great mids and highs already just upgrade the sub in the back. I replaced the head unit in my 90 with Nak and it was a HUGE mistake!! never sounded as good as the factory one

I don't mind the '97 time capsule. Did stick in a portable GPS but other than that, no planned updates. Well, maybe a dash cam but that doesn't enhance the comfort or drivability.

for mine, the temporary solution i did was get a scosche magnetic dash top mount kit and a hidden antenna plug FM adapter. waiting for the amp i want to go on sale so i can move the tablet to the original NAK spot and mount it there but for now, i have hands free calling, music, and maps through an app called Automation: https://play.google.com/store/apps/d...automate&hl=en that emulates android auto. really all i need to make it work is new nak door speakers and my amp, i have the logistics worked out and mounted it even before i realized that i was getting nothing but tweeter. maybe Yamae will have a pinout diagram of the factory nak hookup as i cannot find a good one. Best of luck!

I used a Metra 70-1761 to wire the radio's power, and hard wired to the nakamichi amp harness for the speakers. The Pioneer is powering the door speakers amazingly - sounds OEM. I bypassed the factory amp, so the factory sub no longer works. I have discovered there is a way to wire the amp up, so that will be rewired when it gets warm out.
The dash kit I used was a Metra 95-8153 and yes it is sort of crappy and doesn't really match the dash. This doesn't bother me.
I have Pandora, hands-free calling, and nav directions all handled by my Bluetooth phone thanks to this setup and I have had no issues and no complaints. I spent under $130 (March 2015) and time to install was less than 2 hours on this setup.

I think you did something wrong - your steering wheel is on the wrong side now!

oh and one more thing which is almost a necessity but not technically even 21st century is the valentine one. it's almost impossible to have true peace on the road without one, literally got me out of a ticket yesterday. guy never radared me, claimed he was "clocking" me, i (respectfully) called him out, and no ticket
