Stock nav and aftermarket DD HU
Stock nav and aftermarket DD HU
Can someone clear this up for me?
I have an 05 with stock nav. I would like to upgrade to a DD HU. I've heard that once you upgrade to an after market unit, you lose the voice navigation on the stock nav. Is this true? If it is, is there a way to wire it so you have both?
Thanks
