Need help with Phone Book Transfer

I just bought an 07 Prius and am having issues getting my phone book entries to transfer to the car. I have a Moto Q9c from Verizon that is running Windows Mobile 6.1. I understand the limitation of having to do one at a time but I can't get any of them to transfer. Each time I try to transfer a contact...it tells me it has failed on the Prius display and it tells me it has transferred the contact on the phone. I have seen in one other post someone talking about the need to remove parentheses, will this cause contact transfer to fail? What are all of the format gotchas?
