PCM Programming Necessary?

[gdwiggins]

I recently added the XM satellite radio receiver and a navigation system to my 08 C2 coupe. They both work great.

What, if any, are the disadvantages of not having the PCM programmed by a dealer after installing? It does show that the 2 new items aren't stored in memory.

FWIW, I bought the XM unit new from Sunset. I bought the DVD and Nav unit used on ebay, buying the remaining nav bits from Sunset.

I ended up not having to buy the GPS antenna since the XM unit came with the combo antenna. The TSB for installing NAV was invaluable as it told me what parts and part #s I needed for my car

Total cost of the NAV was $750.

I was surprised everything worked but it did.

Thanks,

Gene
