I just picked up a Z130. I use an iPhone4 and want all the features for the two devices to communicate with each other...A2DP, Pandora etc etc. I was looking at map updates on ebay and it looks like I have to upgrade the OS so I will end up with a Avic z140BH. If I go this route, will i loose any connectivity with my iphone? What are the advantages of this update?
Also, if I try to do the hack/mod of my z130, is it possible to use a garmin map set?
Thanks for any advice
