Hi, I just put the new nav in and hoping for some last bit of advise......
The dealers around here have never flashed a nav unit and don't know if it will take much longer than just a standard radio(because of programming codes, options, etc....).
Is it much harder to get through the options and you maybe know any codes or tips for me I can relay?
Thanks alot for any help on this.

 

See the first post here -- https://chevroletforum.com/m_5604/tm.htm

 

The flash process normally takes about 5 to 20 minutes.

 

Ok, thanks. I read that post, if that's all that's to it, the dealer should be able to handle that easily.
