Kenwood dnx570tr my motorhome system was working fine. now the audio on nav. system isn't working, but the audio on the radio/sirius is working. What's wrong?

If it Sirius capable, get the radio's Sirius satellite ESN, (electronic serial number), from your radio and call Sirius satellite radio and they will tell you what to do. I don't know how to get this number from your unit but in my Lincoln, all I had to do was push and hold the Sirius button on the dash with the radio on and it popped up on the display. Your instruction manual should tell you how to do it. If it isn't compatible, you'll have to buy a Sirius receiver and have it activated with them. Good luck.

I have similar issue. Signal easily lost whenever there isn't a truly clear path to sky. My old cheapie XM radio add-on was MUCH better. I'm taking this back to my dealer tomorrow for other issues with the "top of the line" DVD/NAV/XM system. Such as it won't read the data on most CD's and display names of tracks (maybe 1 CD will display out of 10); and the way the radio truncates the Sirius/XM titles, etc. to much less than the full available screen (my cheapie add on did a better job). For $2,000+ bucks this is a very disappointing audio/GPS system. Sound is mediocre as well. This must be a huge profit center for Toyota -- cheap components + high price = $$$ for them.

Apparently, this auxiliary input only works for a Kenwood CD changer or a sirius radio connection. At least that is my conclusion after finding the same problem. Let me know if you figured anything out on this.

try ebay

Sirius Ready means that there is another piece the company makes that is for sale seperately from the reciever. you need to get the whole sirius system and it will just plug in and play through your existing setup.

Unfortunately KENWOOD codes are not available for free from anywhere on the Internet.

Try your local Radio Decoding Service or Car Radio / Audio Store ...who will connect it to a laptop and read/recode the memory chip (EEPROM)

Debi Mann from Temecula/Murrieta?

Check the fuses. Radio fuse in fusebox (red 10A) and also inline fuses behind radio on red and yellow wire.
Otherwise seek service.

It would help if you supplied the model number of the radio?
Thanks Leadispenser

If you have the factory fitted nav then this is an integrated system and you will need to get the clarion repaired. If you give me a call I can advise you how to arrange to have the unit repaired 0161 428 2020
