I have an annoying phonebook sync issue with my Nexus One and 2010 g37xs w/nav.

When I initially pair the phone and after the phone book is downloaded, if I browse the handset phonebook from the car, names are displayed
Last First
and there are multiple phone numbers for a single name
[other] [main] etc etc.

I've had my Nexus One freshly paired with the car for nearly 2 months now.

Since last weekend sometime (last weekend was the last time I used the handset phonebook from the car, and it was still the same way before) the phonebook entries have been modified so they are now
First Last

However, instead of mlutiple phone numbers for a single name, there are multiple
First Last
entries for those people that have more than one number.

If I browse the phonebook though, there's zero indication which entry is which phone number. I actually have to dial it to see which number it's dialing.

This is really obnoxious and the only way I know to fix it is to re-pair the device, after which at some point, it switches and gets messed up again.

Anyone else experience this and have any ideas on how to make the switch not happen?
