Some people (who I must give full credit to for sending this in, but I don’t have everyones’ email to hand), including Richard Norris and others, have mentioned that they found it difficult to connect the TomTom GPS box to their C500. This is only the “first time connect”.
TomTom have released a fix which sorts the initial problem with the software and after investigation the problem leads to a known issue with the BT Stack on the C500. The patch also updates the TTM for Traffic use. Download it here.
Thanks to the guys at TomTom for this.
