Xbox_fan, I live in south Florida, and it is summer now, if you know what I mean... and the issue is still occurring very often to become annoying.

dls911: what do you mean by reset? Does clicking on the recessed "reset" button on the controller works ? Do you have to turn off the car and restart the car, after the reset to work, or turn on and off the PCM, or does it simply work by hitting the reset ?

I am considering installing a manual power switch to the PCM-Dension (they are connected on the same wire), to power cycle the system when it hangs... just to tell you how frustrated i have become with this issue!

 

The PCM is a total disgrace...and I agree...it is not worth going through all these gyrations just to have a working blue tooth and streaming solution.

I guess that is why I work with the Dension solution. The irony is that my unit on really hot days...will not turn on after I have had my car parked in the sun...without being reset two or three times...but my dealership says that it could be the amp.

I am not convinced that it is my amp...and will not chase this thing any more than I have. The amp issue only occurs a few times a year since I reside in PGH...so I live with this issue until it gets worse.

My E39 M5 from early 2002 had better blue tooth than this car...and that is a disgrace...but I am from the day that Porsche didn't even offer a marginal stereo. Now at least it is tolerable....so for the limited amount of time that I use this car.....I live with it as well.

 

Hi, all, I am just curious that sleep mode and needed to reset is something to do with power source of Dension unit?Did you guys connect the power with PCM or other places?Does the power of Dension get completed cut off at sometime, so it need to be handshake or through initial set up again.
I have used the older Dension unit (no BT, only the ipod player) without any issue at all and I would like to buy the 500SBT, but after reading your comments……… I kind of wondering if Dension 500 SBT is the way to go.

 

After my experience, no, it is not the way to go. I have the same handshake/power up problem on mine, and I cannot recommend this product. I wish I'd heeded the warnings on here and Rennlist, and gone a different route.

 

Exactly what happened to me as well. I will not buy again and will go the aftermarket route next time

Reseting the power to the Dension helps, tried several times when I was still hoping to get it to work reliably. The PCM power should cycle off after 10min if you remove the key, so a manual switch directly to the unit prob helps.

 

I remember Eric@bumperplugs mentioned that Dension unit needs to on constant power.And I wonder if this is could be the issue for sleeping mode.
And can anyone can tell me how to install the microphone or how to hide the wire?I have tried to search on the internet, but couldn’t find any information.

 

The unit needs constant power, but reseting power helps when it fails to connect to the PCM.

The microphone wire can be routed along the a-pillar, up by the windshield and all the way to the rear view mirror.

But sound quality is just awful so skip it, change the dip switches to disable the phone function...

 

I connected initially at the passenger footwell outlet (unswitched). Then I moved it to the PCM slurce (unswitched). Same issue in both sources. This is a 500S BT.

 

Sorry to take so long to post this for you. You take the glove box light out and fish the wires through. You will still need to take out the glovebox though. Easy to reverse if you decide to remove the dension.

 

I decided to put it in my rear center console. I just read this on another thread though, so now I have to make sure this works before having the lightning cable installed in the car:

On your first point, about connecting your iphone to the USB using a lightning cable. This is a known limitation of the 500. You must use their 30-pin cable with an adapter for the iphone 5+.

 

mine actually works real well after i did the latest firmware. the biggest problem i have withmine is the interface is by far the most confusing one ever. i like using the usb thumb drive for all my music. then i use the iphone cable for either plug charging or music play back. i don't use the bt for phone. i would tink the best combo would be the dension for media player then the bt huf for audio.

 

I'm picking up a pattern here...

Hmmm, seems like all the issues are coming from guys who installed it themselves. Why not pay a little extra and get the install done professionally. I had mine installed the same time as I had a passport 9500ci installed, and have had zero issues with the unit.

If it's not install error, the only other conclusion is that some units are faulty and some aren't - and that seems very unlikely, or I got the luck of the draw.

My thoughts anyway, but I could be wrong

 

Pureporsche,
you may have a good point... This a biased sample, though: active participants in these forums are more likely to be DIYers than the national average. The fact that the three who are complaining on this thread, vs the one who is not, does not provide enough statistical evidence to establish trends :-)

That said:
. installing an element in a MOST loop is not rocket science. The loop must close correctly, otherwise nothing works.
. Tapping into power is not rocket science: the installers seems to have gone contrary to the strong recommendations of the manufacturer (switched vs. non-switched), and it might be their own experience dealing with many poor installations at the beginning and learning from it

Do you happen to know a good installer in south Florida, for when I decide to throw out the PCM/Dension combo and replace by a decent audio system ?
