Icelink problems

[zimster28]

Any Advice??? I just had a Denison dealer install Icelink in my 2002 X5 NAV with DSP. I drove home with everything working fine. Stopped for lunch,and started the car up. NAV screen dead and turn signals dead. I unplugged the Icelink cable and NAV screen and turn signals work. I called denison and they said it was a bad unit. Anyone ever run into this?
Also is it true that if i have a 3 pin connector and a six pin connector that i still have DSP. It works without the DSP module that Denison offers. Thanks, just trying to confirm and see if maybe the problem is something else. The above problem is repeatable whenever I connect and disconnect the cable
