Has anyone installed or heard anything about this stereo?

I haven't heard anything about this one. It has a lot of features. It is worth investigating. I wonder if the existing XM module can connect to this one. I have read some other threads on here about a Pioneer system. It seems to be popular.

 

Thats one of the things I was wondering also. If the existing XM tuner and navagation system can hook up to it, so you only need to buy the unit itself.

 

Would be nice if the existing XM and Nav would hookup however by looking at
http://www.oeradio.com/product_GM-5100.html if you look at Features and Specs you have to buy a XM Radio module. Who knows the existing one may be able ot be made to work, companies don't usually make that possible but who knows. I let my XM go when the quality dropped and have a portable GPS so going to have to find away to convince the wife I need this.
