Did you get it sorted? Here is the link to the support page on the Carnetix website, which provides links to the firmware...
after the battery in my car was disconnected for some time i cant seem to get the 2140 to go again. when i plug it in it flashes about 4 or 5 times.
i figured i would try and do i firmware update as i have never done one before and read on these forums that it may help.
the question is how do i do this? when i click the "p2140 firmware v1.8.3" link in the mp3 store under the power supply extended information it just redirects me to the forum.
so where do i get the update and what is the procedure to install it??
thankyou in advance
