2. Please send the link to the latest firmware upgrade for this unit. I tried to install this before but it did not work. Please clarify if the Zip file has to be unzipped in the Root of SD card. If so is it OK just to leave the 'Update' folder at root level OR do I need to get the files inside the folder to root level. Does it need to be a blank SD card, except for the update files? etc. etc. please give good details of procedures!
When I tried previously and went to System Update it did not do anything at all.
3. Radio performance has reduced significantly, and is basically inaudible. Just crackling etc. No change in aerial in the vehicle!
