kingsuv Posted February 6, 2009 Report Share Posted February 6, 2009 The reason you don't want to just "ground out" the 2 wires is one, it's wrong and two, because it can cause the internal latching switch in the unit to fail. Especially when the sequence is switched out of order on a regular basis. After awhile it can cause the screen to flicker back and forth from protection. The Tr-7 is a easy and dependable unit. I personally have installed dozens of them on Alpine units as well as in my own cars. Some of the units I have are a good 7 years old now. Quote Designing, building, and shipping boxes.

I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it. Link to comment Share on other sites More sharing options...

Stallion Marauder Posted February 6, 2009 Report Share Posted February 6, 2009 Alright the word is in! For the price with navigation you cant bet it! On Fleabeay of course snatch one up for the quick 750! which is Navtech but still has the late 2006 map codes. The good part is the navigation drive (NVE-P1) was made to be compatable for the IVA-203 and IVA-505. Basically one of the first all in one Alpine Navigation H/U. Besides that there is a couple bummers which is not compatible with the newest Alpine sound processor PXA-H100 Imprint. Only compatable with the IVA-W505 and IVA-D106 Pop Out. Only feature it has which is Loudness which is somewhat new but not the original MediaXpander feature which doesnt even come in any of the new headunits only in the sound processor. Ok the somewhat downside of this situation is the IVA-203 was made to be compatible with one sound processor and it was the PXA-H701 which was one of alpines best sound processors but dirt ass exxpensive. Also Alpine had stopped making it within the past year. It was the first Alpine 5.1 Sound Processor if im correct. Also 4V Preouts, Time corrections etc the price is almost triple the price of the PXA-H100. Also ive been noticing the navigation drive NVE-P1 sometimes freezes and wont come back on til another half hour. Not even working back up after the reset feature. Anyways Alpine has promised they will release an update the NVE-p1 navigation drive which is updateable within the next couple weeks or month.

Audioguy564 Posted March 17, 2009 Report Share Posted March 17, 2009 TR-7 is very reliable. and yes its a pain if you use 2 switches as everytime you turn your key you have to do it again and again.
