If you get an all in one unit like the 7200, they are a pain to get out if they dont know how, they look built in and will probably damage when removing so according to a few people the little $hits dont go for them....
If you want some security, then you could look at the Kenwood KOS range, they do a v-500 that will fit in your rear cubby, one cable goes to a kos-702 that you can fit in the upper dash cubby, then all your sat nav, ipod, bluetooth plugs into the v-500 in the rear cubby nice and safe... All the bits come up on ebay from time to time. Its touch screen and has a remote that you can control all your bits from... Good think about it being "moduler" is that you can add the bits when you get the cash!
