On setting up from new, adsb showed no connection. Only 3 ports showing on the homepage. Inserted the dongle in the top left port and it was recognised. No room then for the GPS dongle, so swapped it between the wifi one. Problem sorted.
The other problem was white noise on the radio on safetycom. Could not be squelched out. Solved that by swapping the Anker car charger for an old one I had been using before. It is rated at 2.1A . Don't know the make but probably got it at ASDA.
Hope this might help others in setting up.
Next step is to install the new update. Fingers crossed.
