I bought a 2008 nav unit from ebay and 2 dealers later (first one tried for an hour with no luck, second one took 5 minutes) managed to get it coded properly - I think - the Radio/DVD and Nav all work - but I am not seeing any of the Bose options that the manual describes (AudioPilot for one) and I know my 2007 Suburban /LT3 has the Bose option (UQA) so I am wondering if the nav unit is really properly coded? The car does NOT have the Y91 option.

Also - how do I know if I need to mess with the speed sensor wire?

Thanks
