Your on the right path,it's all about the radios. The 130 that I bought, made the Connectivity Group (retail price) at $495, but the 730n has so much built into it that the Connectivity Group is only $170 (probably because Jeep just needs to install buttons at that point). Keep in mind that the price Jeep wants for the old (Alpine) 430n/730n radios is absurd and for half the money you can have a MUCH better navigation touch screen radio installed aftermarket.
Connectivity Group also gives you the EVIC.
Don't forget that the prices your listing and seeing are the full retail prices (sucker prices). Trucar is not a good source for pricing info, it's a dealer paid source like Kelly Blue Book
You should be able to get Connectivity Group and other options at a significant discount and pay somewhere around 2% - 5% BELOW invoice for the JKU. Dealers actually pay somewhere around 7% below invoice. There is nothing you can do about the $995 shipping cost however.
One last thing; Don't spring for the "Max Tow Package" for $500.. Amazon sells the Rugged Ridge hitch and wire loom for $45 and it's exactly the same thing. It also takes about a half an hour to install if you have never seen a tool before. Oh and DOC fees are nothing but pure profit BS.. don't pay them and find a better dealer if they wont wave them.
I have Uconnect.. never use it. Trust me it's worthless and you'll forget all about it a month after you buy your Jeep.
