If the Stealer is claiming the 5th Amendment, then it may be worthwhile checking the different audio manufacturers' websites and making some quick but objective comparisons on the various product trends I've mentioned previously in this thread. You'll only need to check a handful to get a good indication of what's in store... . I would suggest Pioneer, Clarion and Alpine are as good as any.
See what the specs of their equivalent ICE systems are (wrt GPS support which is what this thread started out from) and then make an objective comparison with the MOPAR stuff. If the Stealer is worth everyone of his 5stars he should be doing this for you already, so that he can provide you, the valued customer, with some compelling reasons for why Brand X rather than Brand Y etc, etc.
