Hey, ive done 2 ext cable, one with a motorola charger and 1 with the samsung one....now...the probem is that ive a ericsson chatboard of 6,7 years ago...but how to know what model is? Where is written on?
IIRC, there are 3 Types of chatboards around (ch-01, ch-07 and ch-10), and 01 and 10 should work as a chatboard (both grey). ch-07 doesn´t work IIRC (black one), but i´m not 100% sure.
