Chrysler Stereo Pages at Allpar
Some 2010-2011 stereos used by Chrysler required firmware updates to avoid high power usage on standby, which could drain batteries. There have also been stability and feature-fixing firmware updates for 2011 stereos and navigation systems.
We asked Chrysler about SD card compatibility with their UConnect stereos; we had mixed success with various cards of various sizes. The rep said to get class 2, 4, or 6 cards (not class 10, which is faster), and that 8 gigabytes seemed to be the dividing line between consistent function and problems. This information came in October 2012; firmware updates and newer hardware might change those specs.
Chrysler and windshield radio antennas

From 1968 to 1975, I was Director of Product Planning at Chrysler. During that time Styling (Elwood Engle) lobbied top management to put the antenna in the windshield á la GM. I objected because of the loss in radio performance.
I had a very simple test. My cottage in Mecosta was 160 miles from Detroit and my favorite Detroit radio station was WJR (J. P. McCarthy, Bud Guest, etc). I could get WJR with a mast antenna from the cottage but not with a windshield antenna. I was worried that if the customer experienced this loss in performance that he would blame the reduced radio reception in his new car on the quality of the radio.
Finally in a showdown with Elwood I lost. Management made a compromise decision and that was to put the windshield antenna only on the Imperial - not across all car lines as Styling wanted.
The rest of the story is that after one year's field experience, the Chrysler/Imperial National Dealer Council formally recommended that we return to the fender mounted mast antenna. We did - but we built Imperials with windshield antennas for one or two years. (Eventually, GM also discarded the windshield antenna.)
Footnote: We (Engineering) were not happy with the fragile nature of the telescoping antenna so the Radio Lab (Frank Jenkins, Manager) came up with a fixed length stainless steel mast antenna which was rugged and provided good reception. I approved it. I can't remember the year that the stainless steel antenna entered production but it was when I was Director of Body Engineering (1979 - 1983).
