Thanks for responding to my question. About a year ago I replaced the battery on my car. After that the nav system along with the radio would shut off and the nav system would reboot. This would happen several times while l was driving. I tried the solutions posted on this forum, including disconnecting both battery terminals, putting a jumper between the cables. I even replaced all the fuses on the car, all to no avail. I finally contacted Tanin Electronics. They said it was either a power supply or mother board in the nav. They told me to send it to them for diagnosis. I was hesitant. I really don't use the nav system. I just want a replacement that will fit the vehicle. I just need the screen to display different maintenance, information and rear camera.
I've seen some aftermarket for about $600.00. I don't know which sites are reputable. Any suggestions?

Just a follow up. It turns out that the intermittent rebooting of the nav and subsequent radio shut off while driving was due to the connectors on the amplifier located in the trunk of the vehicle. I disconnected all the connectors located on the right side of the box, sprayed them with electronic cleaner and applied connector lubricant. I reconnected and that seems to have solved the problem. Please do this before you consider buying a rebuilt or new nav unit. Yo will save yourself anywhere from $800.00 for a rebuilt unit to $18,000.00+ for a new one. Wish they would have made these connectors with gold pins.
