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

Upgrading the 130 to a 140 which will happen with the map upgrade will eliminate your voice control for navi so if you value that feature you should avoid the upgrade.

Thanks Vblue is it possible to back up what i have so I can revert back if I don't like the update?

Some of the updates I saw put a Tom Tom map on the unit. Is it possible to putagarmin on it?

That deals with hacks and I am not sure of what is possible for this platform. There are threads that detail what is possible though.
