Help - RNS510 install backfired

[wfdTamar]

I just put in my new RNS510 and Bluetooth kit. Got it in and did some coding in VCDS (which didn't qiuite match any guides but was close enough). Thought it was going ok when I was going through the screens on Setup in the RNS510 and clicked on Maps or Navigation and it was loading something which took ages. I thought it was trying to find the satellites, so I tried starting the car to get out of the shed. No go. Car doesn't even crank over. Now when I turn on the ignition the dash goes crazy, flickering lights and relays behind the dash clicking. The display between the speedo and tacho is blank.

Tried taking out the RNS510 and bluetooth and putting the Audience back in, but same thing. Can't run VCDS because the ignition power won't stay on.

Things I did wrong (but I wouldn't have thought would matter) - didn't have my antenna adaptor yet so I connected one of the antenna cables. I wouldn't think that would have any ill effect, just maybe the radio wouldn't receive (or not as well as it would with both connected).
