Installing The Continental TR7412UB-OR Radio

I use Bluetooth for listening to music from my phone and if I ever needed to charge I'd use the lighter port.
BTW, it seems to have been difficult for some to find a USB lighter adapter for the Porsche socket that fits well. Griffin Technologies manufactures a dual-port USB adapter that fits perfectly. If you Google search, there are a number of discount vendors; however there are inferior counterfeits being sold. I bought mine from Best Buy. Here's a link to the Griffith factory order website: https://griffintechnology.com/us/pro...niversal-micro
Finally, I have had no experience with the Kienzle unit.

One issue that I have found so far is when using a 16gb usb stick and setting to random play it isn't really very random. Sticks on same album/artist for a long time.
I need to dig up a smaller usb stick to see if it has the same issue. I believe the specs on the radio say 8gb max.
Another issue I have found is that my (non-hi-fi) smaller door speakers aren't working. Could be that I never noticed with the old radio though. I don't listen to music all that often so I'll get to that issue when I get to it :-)
Overall it looks "right" and the bluetooth for Waze is really helpful.

Yeah CP, I noted the 8GB limit.
Unfortunately an 8GB USB will hold 1000-1500 normal songs which is way above the 500 limit recommended by Continental.
Must be some internal memory limitations on the unit where it can't keep more than 500 or so songs in memory. Might as well find some 4GB USB sticks and shuffle them in and out.

I have over 800 songs on my memory stick in my Conti, and it works fine.

I love the 7418 I picked up from Tore, but instead of a usb flash drive I use the aux in with my ipod. Actually added a little panel in glovebox with usb jacks for charging things, a jack for the aux input on the Conti radio, and a second lighter socket for good measure.

Unfortunately bringing this back to the top with a problem.
I installed this radio earlier this year (non-hifi car) and it was working great. Didn't use it a whole lot driving but was entertaining while working on the car.
Suddenly I stopped getting audio. Powers up fine, everything works as normal but no audio.
Pulled out the radio and disconnected. This is when I noticed that when I plug in the audio section (connector B), I get audio to some speakers. Hold it just right and I get sound to all speakers. Once I push in the connector more than a couple of mm, I lose all sound.
Sprayed the connections with contact cleaner which didn't help at all.
Connectors look fine on both the radio and the vehicle side.
I don't know anything about car audio, do you think this is a problem with the radio? Not even sure how to check this without another radio.

I haven't seen this before. I guess it is a contact problem between the rear connector and the PCB inside. Anyway not a user-fixable issue. Maybe a warranty claim to the supplier?

Just to close off my issue, there is no problem with the radio.
After lots of testing and determining there was a problem with the right front, I got the right front speaker out and noticed that the previous owner did an unusual (hack) install of Infinity 6000CS speakers.
Looks like if I completely disconnect the RF tweeter, everything works fine. I'll be adding "shopping for new front speakers" to my winter to-do list.
Many thanks to Joe (jansan946) for walking me through the troubleshooting and helpful suggestions for remedies!

ToreB Has Done It Again
All,
I'm bring this back to the top because I recently received a note from Tore Bergvill relating that he has now developed patch harnesses that greatly simplify installation of Continental and other radios into 993's which have the M490 HiFi option.
The "B" block patch harness Tore now offers has integrated line-out convertors (LOCs) that directly interface the installed factory harness. My next project will be to replace the patch harness/crossover solution described in my original post with Tore's LOC harness. Then I am going to reinstall the original Nokia power amp under the passenger seat so that I can take advantage of the door speaker sonics that came with the $930, 6-channel, ten speaker, M490 HiFi option. Here's a link to the BergvillFx site http://www.bergvillfx.com/index.php/...-993-m490.html
Thanks Tore!

Thanks again to both Joe and Tore for all their help with these upgrades. I may do the same as you Joe, but don't know if my amp was working right before I removed it (wasn't sure if it was the head unit or the amp). I guess the easiest way is to just buy Tore's harness and try it.

I sent an email to Tore, but does anyone know if the 996 M490 head unit wiring is the same as the 993? In other words, would that 993 adapter plug and play with the 996 with the M490 and Nokia amp?
I am really liking the look of the Continental unit in the Porsche. I haven't seen another one that looks just as "right" as these do.

The 993 and 996/Boxster M490 connections are the same.
However, the 996/Boxster have by default the illumination input connected to the head unit, but the original 993 head units does not have this. A complete 993 M490 harness must therefore include a separate wire to connect to the dashboard light circuit.
A 996/Boxster harness must include the illumination wire connected to the correct output in the car head unit connector.

Tore
