When using Car Home mode - whether in the dash mount cradle or not - all navigation directions are coming through the earpiece speaker (above the word "Motorola" on the front) instead of the louder speaker-phone speaker (on the back). Totally useless. I have Bluetooth turned off, so that shouldn't be the problem. Turning up the volume only increases the earpiece volume, it doesn't activate the other speaker. Anyone know how to fix this? Thanks.
