Hi there,
iPAQ Repair and Parts offer a comprehensive repair service for iPAQs, Navmans and Acer units (please contact us for a full run down of what we repair).
We offer a free diagnostic, with a speedy and efficient turn around;
it sounds like your 26-Pin connector is faulty (the typical cause of sync and charge failure) which is one of the most common faults with the Navman PiN 570 - we offer a full repair for this without the ridiculous charges quoted by the manufacturers for "non warranty" repairs.
See our Navman PiN 570 Sync and Charge repair at:
